90210 starMatt Lanter is engaged to longtime girlfriend Angela Stacy, E! News reports.

Though he plays womanizer Liam Court on 90210, in real life Lanter, 29, is a true romantic. The actor proposed to his girlfriend of three years last month while vacationing in Paris.

It comes as no surprise that Stacy, who describes Lanter in her Twitter bio as her "very best friend and the love of my life," said yes to her beau — and the 4.2-carat diamond ring couldn't have hurt either.

90210 will move to Mondays at 8/7c this fall on The CW.
