Jennifer Aniston's 50th birthday party certainly was a star-studded event, and plenty of big names were there in attendance. Guests at the Saturday night bash at the Sunset Tower Hotel in Los Angeles included George and Amal Clooney, Ellen DeGeneres, Laura Dern, Robert Downey Jr., Kate Hudson, Demi Moore, Gwyneth Paltrow, Keith Richards, Barbara Streisand and Reese Witherspoon, to name but a few.

But one of the big names spotted there was none other than Jennifer's ex Brad Pitt, who famously split from her in favour of Angelina Jolie when they hooked up on the set of Mr and Mrs Smith. Brad split from Angelina back in 2016, and when he made an appearance at the party, many fans were curious to know what was going on.

However, now a source claims that the pair have buried the hatchet over their prior split. What's more; they're actually getting on quite well these days. The insider allegedly told British tabloid newspaper The Sun that: "They want everyone – all of their A-list mates and their exes – to know they’re on good terms and friendly."

They added: "Brad coming along to a huge event like that was a public move, but he doesn’t care what people think – he and Jen are friends, they support each other and their relationship has come a long way since their divorce, and even since his split from Angelina."

In a recent interview, Aniston opened up about her previous marriages, stating: "They’ve been very successful, in (my) personal opinion. And when they came to an end, it was a choice that was made because we chose to be happy, and sometimes happiness didn’t exist within that arrangement anymore ... This is our one life and I would not stay in a situation out of fear," the 49-year-old explained. "Fear of being alone. Fear of not being able to survive. To stay in a marriage based on fear feels like you’re doing your one life a disservice."

She added: "When the work has been put in and it doesn’t seem that there’s an option of it working, that’s OK. That’s not a failure ... It’s a glass-half-full kind of thing. Always being open. Allowing myself to feel what I feel. What brings me happiness? I have a great job. I have a great family. I have great friends. I have no reason to feel otherwise."

Who knows? Maybe Brad and Jen could be an item again? Maybe they're better as friends? We'll just have to wait and see...
