Unlike Matt Lanter's 90210
character Liam Court, the actor is settling down with the girl of his dreams.
The small-screen cutie, 29, is engaged to longtime girlfriend Angela Stacy, his rep confirms to PEOPLE.
"They are a lovely couple," his rep says.
Lanter – who has previously starred
in the Twilight
parody Vampires Suck
– is currently pining after Jessica Stroup's character Erin Silver on the Beverly Hills, 90210
was the first to report the engagement.
