Saturday Night Live funnyman Jason Sudeikis is definitely serious about his relationship with actress Olivia Wilde. The actor proposed to Wilde shortly after the holidays, PEOPLE has learned exclusively.

“They are so excited,” says a source close to both. “And very, very happy.”

Sudeikis, 37, and Wilde, 28, who has said she fell “blissfully, hopelessly, wildly in love” with the actor, began dating in November of 2011 and moved in together last year.

The couple has been spotted together everywhere from Lawrence, Kan., to Austin, Texas, and most recently in Rome, where Wilde is filming the drama The Third Person.

No word yet on a wedding date.

Wilde will next be seen in The Incredible Burt Wonderstone in March and Ron Howard’s Rush, out in September.

Meanwhile, Sudeikis has the animated film Epic in May and We’re the Millers, costarring Jennifer Aniston, which hits theaters in August.
