The actress celebrated her 50th birthday in Los Angeles on Saturday with a star-studded party that her famous former husband attended
“Brad and Jen have a very civil relationship,” a source tells PEOPLE in this week’s issue. “He would not have been asked to come if that weren’t the case. It was a big night for Jen.”
Aniston spent Saturday night at the Sunset Tower Hotel in Los Angeles to ring in the milestone year. Pals like George and Amal Clooney, Ellen DeGeneres, Laura Dern, Robert Downey Jr., Kate Hudson, Demi Moore, Gwyneth Paltrow, Keith Richards, Barbara Streisand and Reese Witherspoon were all in attendance to help Aniston celebrate.
“The important people in her life gathered to celebrate with her,” the insider says. “Brad fits into that group, and it was natural that he would want to come.”

Though the pair — who announced their split in January 2005 following four years of marriage — embraced at Aniston’s birthday bash, the actress “didn’t really pay any special attention to Brad,” another source adds. “They hugged and chatted for a bit, but Jen was busy making sure all of her other guests had an amazing time.”
