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.

• 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.
