Ruh roh. We’ve just heard that Justin Timberlake was spotted out and about by none other than Lindsay Lohan, smooching on another girl!

The woman wanted for questioning in a jewelry heist — Lindsay Lohan — is now accusing Justin Timberlake of swapping spit with someone other than Jessica Biel.

Lilo allegedly witnessed Timber cheating at Avenue nightclub in New York Monday night — something this blog first put together — and LiLo not-so-cryptically Tweeted about it by saying,

“… where’s jb cheater?” (jb = Jessica Biel)

So the question is … you buying what LiLo’s selling?

She’s also updated her Twitter to say:

Why do people cheat? When love is always standing right in front of their face (s) ?? Sr?

Think she’s one to talk? And do you even think she’s believable?
