How sweet!

Sugarland‘s Jennifer Nettles welcomed son Magnus Hamilton Miller on Thursday, Dec. 6, her rep confirms to PEOPLE.

Baby Magnus is the first child for the Grammy-winning singer, 38, and her husband, entrepreneur Justin Miller.

“We are so thankful for all the prayers and support and are excited to take some time together as a new family,” the couple say in a statement.

And the timing couldn’t have been better: after tying the knot during a small, sunset ceremony in Tennessee last year, the couple celebrated their first anniversary on Nov. 28.

In September, Nettles told PEOPLE she was busy enjoying her last trimester — sort of. “I just feel good to rest,” she said. “[But] things are starting to get a little uncomfortable, if you will!”

Still, after wrapping up touring with her band and performing on the music competition show Duets this summer, Nettles joked, “I’m happy to just have the opportunity to be at home. I’m throwing things away, organizing [and] putting up suitcases. But I’m feeling great!”
