Singer Jewel and her rodeo star hubby Ty Murray are about to become a family of three!

Jewel, who is the co-host for Bravo's upcoming show Going Platinum, found out about her pregnancy on the first day of her new gig. The 36-year-old songbird tells People:

    "I took a pregnancy test and it was positive! It was so hard to keep it a secret. I was worried I'd start throwing up on set and everyone would be like, 'Oh, she's pregnant.' "

The couple tied the knot in the Bahamas back in 2008. As for trying to conceive, Jewel tells the mag it was definitely a process. She adds:

    "I have always been a workaholic, so I had to learn how to slow down and take care of myself in a different way."

Jewel, now in her second trimester, released an album in 2009 called Lullaby ... a collection of children's song.

Their baby is going to love that CD!
