Gerard Butler Licks Katherine Heigl

Gerard Butler licks the cheek of costar Katherine Heigl (in Lanvin) at the premiere of their new romantic comedy, The Ugly Truth, held at Pacific’s Cinerama Dome on Thursday (July 16) in Hollywood.

Gerry, 39, made an appearance on Thursday’s episode of The Tonight Show with Conan O’Brien. When asked about his Bounty costar Jennifer Aniston, he admitted, “We’re very much in love. Especially her. We’re actually going to tie the knot next Tuesday.”

Gerry then let everyone in on the joke, saying, “And then on Saturday, I’m marrying Cameron Diaz. Joan Rivers will be the next weekend.”

The Ugly Truth opens in theaters everywhere on Friday, July 24th.

FYI: Katherine is wearing Joan Hornig‘s Triple Strand Pink Fresh Water Pearls, a David Yurman white and yellow pearl necklace with 18k gold and pave diamond clasp, and Tod’s “Girelli Pochette” clutch in grey snakeskin. Gerry wore a black two button, notch lapel suit and light blue shirt by Dolce&Gabbana. He accessorized with a David Yurman Horse Petrvs Ring in Sterling Silver and 22K Gold,
