Jennifer Aniston, Courteney Cox and More Celebrate Sara Foster's Birthday at Star-Studded Bash

It's happening! And, we can't keep calm! It was more than 25 years ago when six friends were introduced inside a quaint New York City cafe called Central Perk and the rest, as they say, became history. Over the course of a wonderful decade, millions of Friends fans fell in love with Rachel Green (Jennifer Aniston), Monica Geller (Courtney Cox), Phoebe Buffay (Lisa Kudrow), Joey Tribbiani (Matt LeBlanc), Chandler Bing (Matthew Perry) and Ross Geller (David Schwimmer).

We are seriously struggling to believe Jennifer Aniston is 51! The A-lister celebrated the milestone on Feb. 11 with some of her closest pals at the Sunset Tower Hotel in West Hollywood.

Jennifer Aniston celebrated her 51st birthday yesterday—and for the first time, she was on Instagram to respond to the many tributes posted to her. There was a party too, of course: Several celebrities, including Chace Crawford, Elisabeth Moss, Jennifer Meyer, and Aniston's Friends co-star Courteney Cox, showed up at the Sunset Tower Hotel to fête the actress.

Party animals! Jennifer Aniston celebrated her 51st birthday at Sunset Tower Hotel in Los Angeles on Tuesday, February 11, with a star-studded bash including her Friends costar Courteney Cox and jewelry designer Jennifer Meyer.

Jennifer Aniston spent her 51st birthday with her closest gal-pals.

One of the most unrealistic things about Friends is the size of Monica's apartment that Monica, in a fit of post-Richard-breakup-fueled-anxiety, didn't decide to go blonde and then deeply regret it. (Yes, we had that whole episode of Phoebe accidentally cutting Monica's hair too short, but that's not the same.)

Jennifer Aniston recently turned 51. The Friends alum, who is proving age is just a number, took to Instagram to thank her friends and fans who showered her with birthday wishes. Soon after, she was seen stepping out to celebrate her birthday with friends. While paparazzi caught The Morning Show star making her way to the Sunset Tower Hotel in Los Angeles on Tuesday evening to bring the house, fans are keen to know if Brad will be making a guest appearance.

It was our "Friend" Jennifer Aniston's birthday on February 11. The Friends alum turned 51 and it goes without saying, the internet showered her with birthday wishes.

We’re seeing double on Jennifer Aniston’s birthday, and not just because she’s on the cover of Interview Magazine! Courteney Cox, 55, decided to share a photo of herself transformed into a Jen 2.0 in honor of her longtime Friends co-star and pal’s 51st birthday on Feb. 11.

Jennifer Aniston is getting some birthday love from her former co-star! In honor of Aniston's 51st birthday on Tuesday, Courteney Cox shared a twinning snap of her and Aniston.

Jennifer Aniston missed out on the 92nd Academy Awards but the Friends alum was present for the star-studded after party with co-star and friend Courteney Cox. The actresses twinned in black for the night as they attended the after party hosted by Netflix in West Hollywood, California. Jennifer and Reese Witherspoon, for a change, did not make an appearance. The duo celebrated the night with Marriage Story winner Laura Dern who took home the Oscar for Best Supporting Actress. 

Courteney Cox was in the mood to leave everyone teary-eyed, including her BFF Jennifer Aniston. The actress, who is best known for her role as Monica on the American show Friends, takes to Instagram from time to time and shares photos from the past.
