Report: Blake Lively Totally Ganked Ryan Reynolds From Sandra Bullock!

Reports that Ryan Reynolds and Blake Lively are dating are not all that surprising and look to be at least somewhat true. And more than somewhat hot.

But did Lively hijack the hunk from Sandra Bullock?

OK! Magazine claims as much ... likely erroneously.

It's a known fact that Reynolds and The Blind Side Oscar winner are close, but was the good-guy Canadian heart throb actually dating Sandra Bullock?

In what this tabloid calls a "soul-crushing blow," Ryan dumped America’s Sweetheart for his Green Lantern co-star, who recently split with Leonardo DiCaprio.

At 24, Blake is young enough to be Sandra’s DAUGHTER. Shocking.

Only not really. Sandra’s rep denies she and Ryan, 35, were dating, and even if they were, if Bullock, 47, can date Ryan, why can't he date younger too?

It doesn't make any sense. Yet a source SWEARS “Sandra is crushed ... she's trying to act as if she’s not bothered, but the truth is, she’s very hurt.”

“For a while things between [Ryan and Sandra] were going so well, and she really got her hopes up,” the source, conveniently unnamed, adds. “That’s why she surprised Ryan by going to the premiere of his movie, The Change-Up."

"And then last month they had an incredibly intimate trip to her place in Wyoming. But then all of a sudden, Ryan turned around and went cold on her.”

Mmm hmm. We're sure Sandra is on suicide watch.

In recent weeks, Ryan Reynolds and Blake Lively have been seen kissing all over Boston, Mass., where he’s filming his supernatural thriller R.I.P.D.

That much is fact. His romantic connection with Bullock? More than likely tabloid fiction. Still, which actress do you think is the better match for Ryan?
