The '300' actor played coy about his new love, believed to be Romanian model-and-actress Madalina Ghenea, but did reveal they've been dating for several months.

Speaking during an appearance on 'The Tonight Show with Jay Leno' on Monday night (03.12.12), he said, "It's been seven months now... it's not a record."

The 43-year-old actor was first linked to Madalina - who is rumoured to have previously dated Leonardo DiCaprio - earlier this year after they filmed a commercial together for disposable razor brand, Super Max.
