Congratulations, Jennifer Aniston!

The Just Go With It actress is turning 42 today and she's celebrating the occasion by going on a getaway with some friends.

But you don't get a hot body like Jen's by just laying around sunbathing and sipping margaritas while on vacay. She said she'll be working up a sweat...

Her party plan, according to People ? "Get up, have breakfast, have a workout, do something great outside," she said, "If you're consistently working out, your metabolic rate is constantly at a level where it's kind of burning."

Hopefully the birthday girl will have a cupcake and some cocktails after she gets in her cardio.

Jen didn't divulge who will be joining her, but we bet BFF Chelsea Handler might be by her side. The two blonde besties celebrated Thanksgiving together in Cabo.

At last night's Belvedere Red launch party, Chelsea told E! she doesn't understand why people care so much about her friendship with Jen.

"We're just friends," Chelsea explained, "It's not like we're sleeping together...yet!"

Jen also chatted with our own Ryan Seacrest this moring on his KIIS FM radio show, where she confessed her birthday box office wish.

"I don't want anything! I'm an embarrassment of riches," she first told Ry, before adding: "Hey, let's open a movie!"
