Jennifer Aniston’s Birthday Without Justin

Jennifer Aniston celebrated her 49th birthday on Feb. 11 with a big Hollywood bash — but there was no sign of her husband Justin Theroux!

Insiders had earlier feared that Jennifer was repeating her romantic history with Brad Pitt — running off on a romantic vacation with Justin at the end of 2017, just as she did with Brad in 2004 shortly before the couple announced their divorce. But even though Angelina Jolie had already come between them on the set of "Mr. & Mrs. Smith," Brad still showed up for Jen's birthday party in 2005!

Instead, Jen was joined for this birthday pals including stylist Nina Hallworth and Courteney Cox. That's bad news for Jen's marriage, but good news for "Friends" fans — as insiders say that the actress' troubled life has her ready to reunite with the cast of her former sitcom. With "Roseanne" and "Will & Grace" rebooting, Jennifer recently told Ellen DeGeneres that "anything is a possibility."

"Jen really wants to launch a lifestyle brand," said an insider, "but she can't do it right without a big hit. A 'Friends' comeback at 50 years old would be perfect — but the problem is that she always held out, and now Matthew Perry and Matt LeBlanc aren't interested!"
