Katherine Heigl's beauty tends to have an effect on guys - but yesterday, we found ourselves literally swept off our feet by the sight of the good Doctor! Kat was all smiles and sunshine as she made her way through the throng of paps back to her car after lunch at the Ivy (even turning to our camera and wishing us a "Happy X17"!). The competition to snap a pic of the Grey's Anatomy starlet was so intense that our cameraman momentarily lost his footing - although lucky for him, Katherine grabbed his arm to keep him from toppling over. Guess she's just as protective in real life as she is on the show!
