Corey Stoll is now set to wed his girlfriend Nadia Bowers!

The 38-year-old actor, best known for his role as U.S. representative Peter Russo in the first season of Netflix's political drama "House of Cards," is now engaged to Bowers, Us Weekly confirmed.

"Corey and Nadia are such a great couple, she's an amazing support to him," a source told the celebrity and entertainment magazine. "Wasn't shocked when I heard they had gotten engaged."

"Everyone is super happy for them," added the insider.

The couple recently stepped out together at the Toronto International Film Festival on Sept. 6. While mingling with Robert Downey Jr. - who was at the event to promote his new film "The Judge" - the 41-year- old Bowers was seen wearing a beautiful diamond ring, according to Us Weekly.

Stoll and Bowers both starred in "Law & Order: Los Angeles." Stoll played one of the main characters named Detective Tomas "TJ" Jaruszalski on the show, while Bowers appeared as Sandra Miller in an episode, according to IMDb.  

Stoll has been very busy since he became a household name for his performance in "House of Cards" for which he received a Golden Globe nomination in 2013. Earlier this year, he starred in the mystery action film "Non-Stop" as well as in the TV movie drama "The Normal Heart."

He also plays Dr. Ephraim "Eph" Goodweather on FX's vampire horror drama "The Strain," which wrapped up its first season Sunday, Oct. 5. He also landed a major role in the fourth season of Showtime's political thriller "Homeland," which premiered Sunday.

The year will be a lot busier for the New York City-born actor, because aside from wedding planning, the "Midnight in Paris" actor is also currently filming Marvel's superhero film "Ant-Man."He plays villainous character Yellowjacket/Darren Cross in the Peyton Reed-directed film, which is slated for a July, 17 2015 release.

Just recently, Stoll opened up about how it feels to be the baddie in "Ant-Man."

"It's fantastic," he told The Wall Street Journal. "I feel very lucky to be able to go back and forth between playing a good guy and a bad guy. I just started shooting "Ant-Man," but it's already a lot of fun. I think it's going to be good."
