The Boss's Daughter on 'Lie to Me' (VIDEO)

Teen romances are always a little tricky. But they're especially tricky when one of the parties involved isn't actually a teenager. And it's even worse when one of the parties in question is -- well -- the boss's daughter.

And that's the situation on 'Lie to Me' (Mon., 8PM ET on Fox). Emily Lightman (Hayley McFarland) has something of a crush on Eli Loker (Brendan Hines). Unfortunately, Eli is an adult, and Emily is a teenager.

To make matters worse, Emily suddenly kisses Eli while they're having a conversation about a concert. And to make matters even worse, Eli's boss is Dr. Cal Lightman (Tim Roth), an expert in lies and deceit. When Cal finds out that Eli has kissed his daughter -- Cal punches him. And he punches him right in the stomach (or the groin; it's a little hard to tell). Ouch! Don't mess with the boss's daughter!
