It took the media world by storm when Blake Lively was spotted hanging out with Leo DiCaprio in Cannes. The ‘Gossip Girl’ actress and the superstar were seen hugging on a yacht in Cannes, followed by what appears to be a whirlwind tour of Europe together. It’s been more than a month, and no new photos have showed up anywhere. Rumors are rampant that Blake and Leo ended their visibly heated summer romance because of an unexpected factor- Leo’s mother. Blake, who recently starred in ‘The Green Lantern’ alongside Ryan Reynolds, has been a constant media presence lately, due in part to a reportedly fake nude photo scandal. She has also been spotted these days on the set of her hit CW drama, ‘Gossip Girl’, where she plays Upper East Side Manhattan socialite and college student, Serena Van Der Woodsen. Leonardo, on the other hand, is busy filming his latest movie ‘J. Edgar’ alongside ‘The Social Network’ star Armie Hammer. Leo is supposedly very attached to his mother, and various sites are reporting that her opinion on Blake Lively has taken a toll on Blake and Leo’s relationship. However, there are no media reports confirming or denying any relationship trouble, since they didn’t confirm they were in one in the first place.
