Former 90210 star Jessica Lowndes sizzled on the red carpet at the Los Angeles premiere of her new movie "The Prince," in which she stars with Bruce Willis, John Cusack and 50 Cent.

According to the official synopsis, the action thriller is about a retired assassin who is forced to start working again when his daughter is kidnapped. Naturally, he must also "confront his former rival" to get her back.

We've never heard of that plot before.
