Kate Beckinsale [1] is one of the coolest moms in Hollywood [2], but she's not above completely embarrassing her daughter on TV [3]. During an appearance on Jimmy Kimmel Live! [4] on Tuesday, the actress told the host that her 18-year-old daughter Lily has a huge crush on him. Of course, the situation is a little tricky seeing that Lily's dad Michael Sheen (who is Kate's ex) is actually dating Jimmy's ex, Sarah Silverman [5]. "It's very twisted," the actress joked. "It's a sort of horrible, Human Centipede-y vibe." To make things even more awkward, Lily was actually sitting in the audience during the whole thing. Don't worry, though, she smiled her way through it and handled it like a pro.
