The American singer-songwriter and the professional bull rider - who have been trying to conceive for two years - welcomed a son weighing 7lbs 6oz in Texas on Monday (11.07.11) at 7pm local time.
Jewel - who wed Ty in 2008 - announced the birth news on her website, writing: "Ty and I are so pleased to welcome our new baby boy into the world. We are overcome with happiness - it really is as great as everyone told us it would be - better even!"
The 37-year-old beauty - who released children's music album 'Lullaby' in 2009 and is set to bring out another kids' record this autumn - previously revealed she was "worried" about letting it slip she was expecting by being sick.
She said: "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.' "
