Having been dating Mark Cornelson since February
, T.R. Knight has formed some perspective on their relationship – and their age difference.
"It's bound to raise some eyebrows," the 35-year-old Grey's Anatomy
star tells Extra
for an interview due to air Thursday, "but we love each other."
Cornelson, 19, is a student and "an amazing guy. I love being around him," says Knight. "I love what we have."
With a laugh, the actor also says, "I was surprised he was interested!"
Despite the legalization of same-sex marriage in California – which has prompted Ellen DeGeneres
and Star Trek
vet George Takei
to announce (separately) that they intend to wed their respective partners – Knight has no similar plan for the immediate future.
"We've only known each other for six months, so I think it's a little soon to consider marriage." Still, he says, "I don't think you date anyone that you don't see a future with."
Asked if he's interested in having children: "The idea of it, yes," he responds. "Adopting."
