Blake Lively and Ryan Reynolds at Comic-Con in San Diego in 2010

Blake Lively is having mom problems. Specifically, Ryan Reynolds' mom Tammy. During a recent visit with Ryan to his parents' house in Vancouver, Blake got into it with Tammy and ended up gutting her like a fish with a dull butter knife. OK, not really. But I bet she would have if it was legal. From Star:

"Tammy would like to see Ryan with a women who's not in the movie business because she feel that, ultimately, actresses put their careers first," says the source. "And she thinks Blake is pressuring Ryan into settling down before he's ready. He [also] rushed into his first marriage, with Scarlett Johansson ... [Tammy] says when they have kids, Blake and Ryan should raise them in Canada because it's safer. Blake refuses to even consider that, saying that she has to be in New York for work."

The mama drama came to a head during a May 6th dinner at the Reynolds family home.

"When Tammy started grilling her, Blake left the room and had a meltdown," says the source. "She told Ryan she wanted to stay at a hotel for the rest of the trip ... Tammy says it proves she's right: Blake's a diva. Ryan is torn between them - and in an impossible position."

Blake needs to be really careful, here. Mother dearest Tammy wants these two solid B-listers to give up their careers and move to Vancouver, B.C. Do you know what that means? It means that Tammy is a raving lunatic who has no problem killing Blake and leaving her dead body in the snow for the moose to devour. Tammy will not accept her baby boy having his heart broken again, that just won't do, eh. And that leaves Blake with one choice: She must dump Ryan and then have sex repeatedly with me. Yup, it's a foolproof plan. Especially if you're me.
