The time has come for Jewel to sing lullabies.
The singer and her husband, professional bull rider Ty Murray, welcomed a son, Kase Townes Murray, on Monday evening in Texas, their rep tells PEOPLE exclusively.
Kase arrived at 7 p.m. CST and weighed in at 7 lbs., 6 oz.
"Ty and I are so pleased to welcome our new baby boy into the world," Jewel tells PEOPLE. "We are overcome with happiness – it really is as great as everyone told us it would be – better even!"
Jewel found out she was pregnant on the first day of her job co-hosting Bravo's reality show Platinum Hit
. "I took a pregnancy test and it was positive!" she told PEOPLE. "It was so hard to keep it a secret."
The Grammy-nominated singer, 36, who had struggled to conceive, was hit by a fire truck
in March at five months pregnant. She was released from the hospital after tests concluded she and her unborn child were unharmed.
The couple, who live on a 2,200-acre farm in Stephenville, Texas, have spent the spring converting a guest room in their home into a nursery. Jewel has also been working on a new children's album, The Merry Goes 'Round
, out in August.
Jewel and Murray – co-founder of the Professional Bull Riders, nine-time world champion and a color commentator for Built Ford Tough Series broadcasts – wed in a beach ceremony
in the Bahamas in 2008.
