Happy Birthday Madonna/JamesCameron/KathieLeeAndFrank

If we had a cupcake for every celebrity birthday today, we’d be on one heck of a sugar rush. (Also, our pants would probably feel too tight.)

Of course, August 16 is far from the only day boasting the birth of a number of the celebrities you love and the celebrities you just love to hate, but there are quite a few celebrating another year older today. We couldn’t help but notice the varied ways these famous names have taken to recognizing the day they were brought into the world.

For example, if you’re Madonna – who turns 52 today – you would party in London over the weekend in celebration of looking not even close to the age you actually are. The pop icon hit up the Shoreditch House in East London with daughter Lourdes, 13, in tow. It seems her special friend, Jesus Luz, also made an appearance.

And if you’re James Cameron, who turns 56 today, you would take some of the profits from “Avatar” and send yourself to Russia’s Lake Baikal, reportedly the world’s oldest and deepest lake, according to People. Cameron apparently explored the bottom of the lake in a Mir mini-submarine, the same kind he used when he was filming “Titanic.”

We’re sure that Cameron’s underwater extravaganza is an exhilarating way to spend a birthday, but Kathie Lee Gifford and Frank Gifford – who turn 57 and 80 today, respectively – went with the simple celebratory approach of having their cake and drinking with it, too.

We’d also like to sing a special, Stevie Wonder-version of “Happy Birthday” to:

Steve Carell, who turns 48
Vanessa Carlton, who turns 30
Angela Bassett, who turns 52
Timothy Hutton, who turns 50
Rumer Willis, who turns 22

If we left your favorite star of the list, we hope you (and that individual) will forgive us, and that you'll have some cake for them in our stead.
