LOS ANGELES - Rush actress Olivia Wilde is pregnant and expecting her first child with fiance and Saturday Night Live veteran Jason Sudeikis, People magazine reported on Sunday.

The 29-year-old actress, who first gained wide attention as Dr. Remy Thirteen Hadley on Fox television's medical drama House, met Sudeikis, 38, on the 2011 season finale of SNL and they began dating six months later.

They became engaged in January of this year, according to People.

"They are incredibly happy," an unnamed source close to the couple was quoted as telling the magazine.

People magazine said representatives for the couple confirmed that Wilde is pregnant with their first child, but there was no word on a due date.

Earlier this year, Wilde told fashion magazine Marie Claire that she was excited about starting a family with Sudeikis in the future, saying, "He's so good with kids. ... I'm open-minded about how many, but three is like a little party."

Both performers have been previously married and divorced - Sudeikis to television writer and producer Kay Cannon and Wilde to documentary filmmaker Tao Raspoli. Those unions ended in 2010 and 2011, respectively, without children.
