Major relationship news out of Gossip Girl land! It appears Blake Lively (Serena) and Leonardo DiCaprio have split! The reason? According to sources: Leo's mother.

Apparently, Blake flew to Italy to meet Leo’s mom, but she "couldn't stand" the 23-year-old Gossip Girl starlet.

A source told Now: "Blake's a total mess. She tried hard to impress Leo's mom when they met but Irmelin couldn't stand her. She told Leo that Blake was far too up herself for him. Blake was nervous so she did talk a lot. But his mom says all she did was talk about Gossip Girl and how she's a Chanel model.”

This matters because Leo is a bit of a momma’s boy. "Leo listens to his mom and the fact that she didn't like her has put him off."

Sad! Is this the end of Blake and Leo?
