Jennifer Aniston Just Posted THIS Hot Picture On Instagram. She's 51!

Good Lord! From Jennifer Lopez, 50, looking hot as ever at the Super Bowl to THIS sexy post from Jennifer Aniston on Instagram who just turned 51!! She said, "Thank you @interviewmag for this birthday surprise. I had no idea this would be coming out today. Feeling proud and honored to be celebrating with this cover. Thanks to the Interview team for celebrating women at every age...turns out 51 is pretty fun."

Aniston's good friend, and Friends co-star Courtney Cox, also showed up at her birthday party looking EERILY like her, but said, "There's only one Jennifer Aniston." As for her diet (cause you KNOW I had to do a deep dive!) she sticks to healthy, organic fruits and vegetables and whole grains; lots of eggs and lean proteins. Here is a link where she was interviewed specifically about her diet.

Happy 51st, gorgeous girl!
