Move over Kate Middleton there's a new celebrity baby mama in town. Sugarland singer Jennifer Nettles is now introducing her baby boy Magnus Hamilton to the world. Nettles had Magnus, with husband Justin Miller, back in December and in light of Mother's Day, felt the need to show him off to the world, revealing the first photo of the baby on her own official website.

"So much love and joy on my first Mother's Day! A very Happy Mother's Day to all the Mamas!" Nettles tweeted.

It seems like the Sugarland singer is enjoying and adapting to motherhood quite well.

"I'm so excited!" Nettles recently told People magazine. "He's super, super sweet. We made a deal before he was born. I said, 'Look, you can cook as long as you want, as long as you come out and latch like it's your job and have a sweet demeanor.' He kept his part of the bargain!"

Later in the interview, Nettles revealed her Mother's Day plans consisted of sharing brunch with the 5-month-old baby.

"It's a good time around naps," she said. "We'll do a nice brunch and just relax."

We wish Jennifer Nettles, baby Magnus and her husband Justin all the best on their journey through parenthood [as long as Sugarland continues to put out great music].
