Shenae Grimes by Michael Desmond/The CW Shenae Grimes by Michael Desmond/The CW

If Gossip Girl's Penn Badgley was looking for a feud when he told the 90210 girls to " eat a cheeseburger," Shenae Grimes isn't biting.

Into the feud, that is. No word on the cheeseburger.

The actress, who plays Annie on 90210, had this to say to Extra about complaints she's too thin: "Shake it off, baby!"

Grimes and castmate AnnaLynne McCord also sidestepped talk of a clothing rivalry with the Gossip girls.

"We beat the makeup by far, I'll tell ya that! But oh my god, Leighton [Meester] - I love her. She rocks that show," McCord said.

Everyone's getting along so well that Grimes is down for a crossover with her fellow CWers: "We have been talking about that since day one," she said.
