Megan Fox locks lips with Dominic Monaghan

Washington: `Transformers` star Megan Fox recently locked lips with `Lost` star Dominic Monaghan.

However, the newly-married star was not cheating on husband Brian Austin Green.

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

Fox and Monaghan`s roles are reportedly 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," quoted a source as telling E!.

"Then they fight but end up having sex again."

The source added that the video, which also reportedly stars Rihanna, - is `gritty` with `lots of passion`.
