Jennifer Aniston and Courteney Cox celebrate close friend Lisa Kudrow on her 60th birthday

Some friendships are worth keeping in life forever. No matter what, good "Friends" will be "there for you." As Lisa Kudrow celebrates 60 years of her existence, her "Friends" co-stars Jennifer Aniston and Courteney Cox celebrate their long-time friend's birthday. They took to Instagram to share throwback photos of themselves with Kudrow over the years, including one taken on the "Friends" set, which was rebuilt for the "Friends: The Reunion" special in 2021. 

54-year-old Aniston captioned her Instagram post, which included photos of herself, Cox, and Kudrow hanging out together, "Please join me in celebrating one of my favorite people on the planet. LISA KUDROW! She’s been my friend and my family for nearly 30 incredible years. I cherish you…I love you, my sweet Floosh. One of the most talented comedians/actors I’ve had the great honor to work with for all these glorious years and more to come! Happy Lisa’s Birthday!" to which Kudrow responded, "My Joooiest Joooo I love you beyond my dear friend forever!" 

While addressing Kudrow by her nickname, Cox also dedicated a  to her. She wrote, "Happy birthday, my Loot. This is my second attempt: ChatGPT didn’t give you nearly the amount of love I feel for you. You are the smartest, funniest, most thoughtful person. I always feel seen and loved when I’m around you. That’s the gift you give to those you love x" The post also showed Cox and Kudrow relaxing at home and snuggling with one of Cox's dogs. "Oh Cahoot. I love You so much and guess what? I always feel seen by YOU," Kudrow replied.

Kudrow's 60th birthday comes just weeks after her former co-star Cox celebrated her 59th birthday on June 15. "Thanks for all the happy birthday wishes," Kudrow wrote on her Instagram Story as she posted a photo of herself with her eyes closed in front of a 60-shaped candle-lit birthday cake. "This wish for all of you!"

The "Friends" actresses have remained close since the show's conclusion in 2004 and continue to have each other's back. In February, Kudrow and Aniston gave a joint speech in support of Cox when she received a star on the Hollywood Walk of Fame. Hearing her longtime friends during the ceremony felt "great," Cox shared with PEOPLE, adding, "They're such wonderful friends of mine and they're family to me, so it felt really comfortable... they're my sisters." Cox and Aniston had reunited in April 2022 wearing matching "Friends Forever" shirts to promote a clothing line based on the final four seasons of the beloved sitcom. The two shirts worn by the longtime friends had a set of six keys around the words, symbolizing the series' final scene in which all six friends left their keys behind when Monica and Chandler (Matthew Perry) moved out of their apartment. "Friends" aired on NBC for ten seasons from 1994 to 2004. Friends stars Aniston (Rachel Green), Cox (Monica Geller), Lisa Kudrow (Phoebe Buffay), Matt LeBlanc (Joey Tribbiani), Perry (Chandler Bing), and David Schwimmer (Ross Geller) reunited for the HBO Max special "Friends: The Reunion."
