'Brad’s fallen for Margot and he’s fallen hard,' noted the source.
And during the promotions for the movie the source claims that the pair sneaked off for a quiet dinner.
The friendly vibe between the two is so evident that Margot’s husband Tom Ackerly is starting to feel irritated, claims the magazine.
'Margot’s constantly singing his praises – she’s always Brad this and Brad that and it can drive poor Tom crazy!' the publication's source claims.
Life & Style even claims friends are worried that Brad will repeat the same mistakes when he fell in love with Angelina while filming Mr & Mrs Smith while still married to Jennifer Aniston.
'Those close to him are praying that he’s learned from this messy love triangle.'
Neither Brad nor Margot have responded to the publication's out-there claims, but Hollywood insiders agree Margot and Tom's marriage is rock solid, and she 'would not be interested in Brad' beyond friendship.
