Brad Pitt sends Jennifer Aniston his congratulations on her engagement
The 48-year-old star spoke with his ex-wife, who he split from in 2005, to say how pleased he was to hear the news she is marrying actor Justin Theroux, who proposed at his 41st birthday dinner last Friday
A source told the Daily Mirror newspaper: "Brad gave Jen a quick call to say how pleased he was to hear that she was getting married.
"He jokingly asked if he should 'save the date', and they both laughed, but told her in all seriousness that he was really happy for her and Justin.
"He wished her luck and told her he hopes they're very happy together."
Brad is also set to marry his partner, Angelina Jolie - who he started dating shortly after splitting from Jennifer - in the coming weeks, and she also wished him well.
The source added: "Brad and Angelina are due to marry in the next few weeks and she wished him all the best for his wedding, too."
Although Jennifer, 43, and Brad don't speak too often, it is thought his mother, Jane, may still get an invite to her wedding, as they remained friends after the separation.
The source said: "Brad and Jen don't get in touch that often as they've both moved on with their lives.
"Jen does still chat to his mum, Jane, so there are rumours in Hollywood that she will make an appearance at the wedding.
"But the guest list hasn't even been started yet, so it's too early to say for sure."
