Fellow movie-goers might not have noticed actor Vince Vaughn and fiancée Kyla Weber out for a matinee in Santa Monica over the weekend had it not been for the huge bauble on her left hand.
The 38-year-old actor proposed to Weber, a Calgary Realtor, with a diamond ring reportedly worth $125,000. “It’s magnificent,” fellow Realtor Sylvia Smith told local paper, Sun Media. “It’s a great big diamond surrounded by other circular diamonds.”
According to sources, no wedding date has been set but Weber, 29, recently relocated to L.A. “They’re both very excited,” adds a source close to Vaughn. “He’s a simple, Midwestern, good guy and she’s very down-to-earth, which is exactly what Vince is all about.”
The actor is currently in post-production on the comedy Couples Retreat, costarring pal Jon Favreau.
