Brad PittBrad PittWhat's all this, then?

Brad Pitt has had a romantic reuniting with a former lady love.

Shock, horror.

But it's all in the name of work.

Brad has coupled up with Gwyneth Paltrow for their upcoming movie, Dirty Tricks.

And somebody is not shouting it from the rafters... US whisperings are that Angelina Jolie is none too happy about the pairing.

Maybe she feels it's a little close to home - Brad and Gwynnie will apparently be playing a Mr and Mrs in the flick.

Which they nearly became in real life before they broke off their engagement in 1997, after a three-year love affair.
