Pitt attends Aniston's birthday bash

Jennifer Aniston's ex-husband, Brad Pitt, attended her 50th birthday party. According to reports on People.com, the 55-year-old actor was spotted making a low-key arrival at the event, which took place on Saturday night at the Sunset Tower Hotel in Los Angeles, California. While Aniston and Pitt had remained friendly over the years, a source said the two weren't especially close. "They aren't in regular contact, beyond an occasional text back and forth to wish each other the best when there's been a new project or big event," the source revealed.

Other stars including Katy Perry, Orlando Bloom, Gwyneth Paltrow, Ellen DeGeneres, Jason Bateman, Jennifer Meyer and Reese Witherspoon were also spotted at Aniston's party. Meanwhile, Angelina Jolie's father, Jon Voight, recently spoke out about how his daughter and her family are going amid their ongoing custody battle over their six kids, reports USWeekly.com.
