Being a dad? “It’s a beautiful thing,” Constantine Maroulis tells PEOPLE.

“It’s part of life,” says the 2005 Idol alum, as he walked the red carpet Sunday at CC Sabathia’s 30th birthday party at New York’s 40/40 Club with his girlfriend (and mother of his baby-to-be), Angel Reed – whom Maroulis met last year while the two were starring in the Broadway musical Rock of Ages.

In preparation for his paternal duties, the Brooklyn-born singer, 34, says he’s “just living every day right now, trying to do good work and provide for family long term – so I’m looking forward to the road ahead, definitely.”

Besides meeting Reed, there are other perks to starring in a Broadway show: “A lot of Yank[ee]s are big fans of our show,” says Maroulis. “We had A-Rod there.”

Reed, who has been part of the Rock of Ages ensemble since its 2008 pre-Broadway runs in Las Vegas and off-Broadway, reportedly gave her notice after becoming pregnant.

Meanwhile, Maroulis – who’s still rockin’ in the show at Broadway’s Brooks Atkinson Theatre – is scheduled to reprise his Tony-nominated role as rocker Drew in the show s national tour, which opens in Chicago Sept. 21.
