Lizzy Caplan engaged to English actor Tom Riley

LOS ANGELES, July 25 (UPI) -- Lizzy Caplan and boyfriend Tom Riley are engaged.

The 34-year-old American actress and 35-year-old English actor got engaged in May in New York, Caplan's rep told news outlets after the star was spotted wearing a diamond ring Friday.

Caplan and Riley met in January 2015 while the actress was filming in London and made their red carpet debut as a couple at the Prague Opera Ball this past February. Caplan was open to having children when she spoke to Elle Canada in 2014 but dismissed traditional gender roles.

"I don't want it to be an assumption that I will be the one to stay at home and raise the kids," she told the magazine. "I really want kids, and I want to be fully involved in their lives, but I don't want to sacrifice my own goals to be a mother."

"I actually romanticize the idea of a stay-at-home dad," the star revealed. "Partly because I think that's a very sexy thing, but also because if there are two working actors and both of them get a job and they have a baby, the woman is going to stay with the baby. I see it all the time. It just seems very unfair."

Caplan is known for playing Janis Ian in Mean Girls and Casey Klein on Party Down. She presently portrays Virginia Johnson Masters of Sex, which will return for a fourth season Sept. 11 on Showtime.

Riley, meanwhile, played Leonardo Da Vinci on the Starz series Da Vinci's Demons. The actor will star on the new Amazon Prime drama The Collection with Mamie Gummer.
