Brad Pitt has extended an olive branch to Jennifer Aniston after apparently congratulating his ex-wife on her engagement to Justin Theroux.

It was revealed earlier this week that 41-year-old Theroux popped the question to Aniston on Friday last week.

Following Aniston’s infamous divorce from Pitt in 2005, it seems she had finally moved on and found her Mr Right.

But while some cynics claimed their engagement news was a move to steal the thunder from Pitt, who is due to marry Angelina Jolie this weekend, the Ocean’s 11 star doesn’t appear to feel the same way.

The 48-year-old, who was married to Aniston for five years, even joked about being a guest at their upcoming nuptials.

‘Brad gave Jen a quick call to say how pleased he was to hear that she was getting married,’ a source told the Daily Mirror. ‘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.’

It was reported Justin popped the question on Friday, which also happened to be his birthday.

Although it was originally reported he asked for her hand in marriage on the set of her new film, it has now being claimed it was at the Blue Hill restaurant in Greenwich village, New York.

His spokesman confirmed the news to People magazine: ‘Justin Theroux had an amazing birthday on Friday, receiving an extraordinary gift when his girlfriend, Jennifer Aniston, accepted his proposal of marriage.’

Pitt is now due to marry Jolie, who he starred alongside in Mr and Mrs Smith just before announcing his divorce from Jennifer, in a French ceremony this weekend.

And the former Friends star is also said to be happy for her ex, with the source adding: ‘Brad and Angelina are due to marry in the next few weeks and she wished him all the best for his wedding, too.’
