Megan Fox Kisses Another Guy

Megan Fox locked lips with Lost alum Dominic Monaghan Friday in L.A.

No, the newlywed wasn't cheating on new husband Brian Austin Green.

She was just shooting a cameo in Eminem's
upcoming video "Love The Way You Lie
."

E! News reports that their roles are inspired by Eminem's relationship with ex-wife Kim (whom he married and divorced twice).

"Things start off with a sex scene between Megan and Dominic," a source tells E!. "Then they fight but end up having sex again."


The source says the video (directed by Joseph Kahn) -- which also reportedly stars Rihanna -- is "gritty" with "lots of passion."

The couple tied the knot on the beach in Hawaii with Green's son, Kassius, as witness on June 24. Earlier this year, Fox told Us, "We are just even more committed to each other and we always have been. I am more in love with him now than I was in the beginning."
