British TV presenter Lisa Snowdon finds dating movie superstar George Clooney tough - because she's afraid to share secrets about the "Ocean's Twelve" hunk with friends.

According to the New York Post, the leggy beauty would love to gossip with girlfriends about her relationship with Clooney but is too afraid to divulge any of his dark or embarrassing secrets.

"With a new boyfriend you want to go: 'Guess what - he did this and this.' But I couldn't talk. I had to be so careful."
