The plot is nothing new, but, with leading men like Ryan Reynolds and Jason Bateman, we can't wait to see this weekend's "The Change-Up."

The two men make the fateful wish to switch lives - one trades in his playboy lifestyle for that of a family man, and vice versa.

Here's what else is happening this week:

Sunday:

• It's finally here! Discovery Channel's "Shark Week" kicks off its annual week of exciting - yet educational - programming at 9 p.m. ET. Don't forget to check out our interview with Chief Shark Officer Andy Samberg.

• To celebrate the 30th anniversary of MTV, VH1 Classic is airing a marathon weekend of the network's programming, concluding with the first hour of its 1981 launch Sunday at midnight.

Monday:

• Lady Gaga is performing and acting as a co-host on "The View" at 11 a.m. ET. The pop star is expected to sing her latest single, "You and I."

Tuesday:

• Greyson Chance - the talented kid who kicked-off his career with millions of YouTube views - releases his first album, "Hold On 'Til the Night."

• There might only be 12 episodes, but you don't want to miss catching up on season 3 of "United States of Tara." Toni Collette is hilarious in the award-winning show.

• The movie based on surfer Bethany Hamilton's inspiring story, "Soul Surfer," comes out on DVD. Carrie Underwood also displays her acting skills in the summer flick.

Wednesday:

• Since leaving the "CBS Evening News," Katie Couric will head to daytime TV on "The View."

Thursday:

• With all her success, it's still a surprise that Pia Toscano didn't make it further on "American Idol." The singer will promote her new single on "So You Think You Can Dance," which will also feature Christina Applegate as a guest judge.

Friday:

• "Rise of the Planet of the Apes," a remake of the 1968 original, stars Freida Pinto and James Franco. Between his TV guest roles and other movies, 2011 has been a busy year for Franco.

• It's opening in limited release, but, if the trailer is any indication, "The Whistleblower," starring Rachel Weisz, will showcase an effortlessly stunning performance. Check to see if it's in a theater near you.

Harry Belafonte, at 84 years old, is still making headlines.

On Thursday, CNN talked with the actor/humanitarian/activist at the Television Critics Association Tour in Beverly Hills. He was there to promote his upcoming HBO documentary “Sing Your Song," which chronicles his longstanding career and work alongside many notable civil rights activists.

But what caught our attention during the interview were his outspoken words on President Obama and the current budget impasse.

Scarlett Johansson is the latest star to get an invite to the Marine Corps Ball, according to People.com. Unfortunately for Sgt. Dustin L. Williams, ScarJo already has plans for November 10.

"In my absence, I raise a glass to you and all the men and women of the U.S. Marine Corps, past and present, in thanks for your continued commitment to preserving the safety of our nation,” the actress, 26, writes in a statement to Zap2it. And graciously, Johansson is sending the soldier a case of Moët and Chandon to ease the sting of rejection.

Really, I was just happy to know he made it this far.

Thursday night's episode of "So You Think You Can Dance" marked the end of the road for Jess LeProtto, as voters rallied to keep Ricky in the competition (which once again goes to show that the voters can and will change their patterns late in the season).

Jess was definitely one of my favorites, the best Broadway dancer we've seen in the history of the series. Even so, it had to be an uphill battle for him to make it all the way to the top 8. When he spoke to reporters on Friday, however, he disagreed that he might have had an especially hard time.

Amy Winehouse may have reached out to Dr. Drew Pinsky before she died on Saturday.

When former model and "Celebrity Rehab" contestant Janice Dickinson stopped by Pinsky's HLN show on Wednesday, she told Dr. D that she took the liberty of passing his number along to a member of Winehouse’s camp.

Though Pinsky says no contact was ever established between him and Winehouse, or any member of her camp, for that matter, he told KROQ on Thursday he recalls receiving a missed call from an unknown international number.

David Letterman used Kirstie Alley’s recent “Dancing with the Stars” stint to get some laughs on his show, but the “fat actress” wasn’t going to let it slide. While visiting the “Late Show” last night, Kirstie called Dave out for calling her fat.

“I feel a little estranged from you,” Alley shared on the show. “I thought you loved me madly, but then you would talk about me being sort of… chub.” Dave offered an apology, admitting, “I did make jokes about the weight.”

But it wasn't about to end at that - Kirstie came prepared to read Dave’s jokes, including this zinger: “Kirstie Alley joining ‘Dancing with the Stars’… if you don’t already own one now might be the time to get a wide-screen TV.” Ouch!

“We do love you,” Letterman explained, saying he thought he had the actress’s approval for weight-related jokes. “If you were skinny, we’d tell jokes about you being skinny… well, probably not.”

The music industry lost a huge star, Katie Holmes lost weight and Kristen Cavallari lost her fiance (and her dignity?).

Cavallari probably regrets that wedding dress photo shoot now that she and Chicago Bears quarterback Jay Cutler have called off their nuptials, but at least we can see what she might have looked like walking down the aisle in this week's Life & Style.

And, this just in: Katie Holmes is among the many celebrities who are too thin.

J.Lo appeared on multiple covers this week. Thanks to People, Life&Style, Us Weekly and OK!, we now know Lopez spent her birthday without Marc Anthony, she's been partying and she's plotting her revenge.

Oh, and did we mention Denise Richards regrets having her breasts done... each time, that is.

Until next week...

If you miss wearing plaid flannel (even in summer), and harbor an urge to scour your local beauty supply store for some crimson glow hair dye, you may want to check out reruns of "My So-Called Life" on Sundance Channel.

If you blinked during the 1994-1995 television season, you might have missed the ABC teen drama which lasted a mere 19 episodes and starred Claire Danes as 15-year-old Angela Chase and Jared Leto as the object of her affection - Jordan Catalano.

Jordan. Catalano. Two words. It was never just Jordan. This was just one of the quirks that made "MSCL" so great - there were so many things just for the fans. Remember Tino? You couldn't possibly remember Tino - lead singer of Frozen Embryos/Residue - because you never saw him. FULL POST

There are rumors that the film version of beloved '80s cartoon "Smurfs" is a dud, but it may be worse than anyone could have imagined.

“The Smurfs” managed to maintain a shocking 0 percent rating on film review site Rotten Tomatoes for the past week, just recently bumping up to a mere 20 percent.

Despite the talents of Hank Azaria, Neil Patrick Harris, George Lopez and Katy Perry, the negative reviews are rolling in. Critics are calling the live-action/animated flick a wreck.
