As the ink still dries on the divorce of Avril Lavigne and Sum 41 lead singer Deryck Whibley, Whibley was seen dining with young, up-and-coming model Hanna Beth Merjos in Vegas this weekend.

As reported by OK! Magazine, Whibley and Merjos were seen sharing dinner at Las Vegas hotspot Stack in the Mirage Hotel this Friday, holding hands and acting "cuddly," according to a source at the event.

Later on the two headed out to nightclub Jet, where Whibley was seen pouring vodka cocktails and dancing to the Kings of Leon song "Use Somebody" with his new lady.

If you expect Lavigne to be jealous, think again. According to a source speaking to OK!, she's "unfazed" and that the two's marriage had been "over for a while."
