Hollywood power couple Brad Pitt and Angelina Jolie's much anticipated wedding may clash with that of the actor's former wife Jennifer Aniston with Justin Theroux.

According to report in Sun, Pitt received a wedding licence at the end of February, which stated they must marry in 90 days. It is apparently the same time when the Friend's actress is planning to tie the knot to the screenwriter.

"Brad and Angelina left themselves short of time to sort out their wedding because of the licence deadline. A few months is nothing when you're planning a wedding - especially one as major as theirs," a source said, "Everything points to them getting married in May just after the Cannes Film Festival ends, because they've got their hearts set on tying the knot in France."

There were previous reports claiming that Aniston will be attending the duo's wedding.

"All that goodwill would go out the window if Brad's wedding date comes close to hers. Jennifer will see it as an attempt to upstage her and there will be a battle over Hollywood guests," the insider added, "She knows they will be judged on who had the better wedding by pulling in the biggest stars."

The Mr & Mrs Smith stars have been together since 2005 and were engaged last year in April. The couple had previously settled a 16th century French château as the venue for their wedding too.

Jolie was previously married to actors Jonny Lee Miller and Billy Bob Thornton. Jolie and Pitt reportedly became close on the sets of the film Mr & Mrs Smith, while he was still married to Aniston.
