Sunday was the first Mother's Day for Sugarland singer Jennifer Nettles. She celebrated the holiday with another big first -- she debuted her son Magnus Hamilton Miller, born Dec. 6, 2012.

Fans had been wondering when Nettles would reveal an image of her pride and joy. Now that she has, we can finally gawk and "ooh" and "ahh" with reckless abandon. The songstress tweeted an intimate photo of herself with her little guy, who is clearly the love of her life.

"So much love and joy on my first Mother's Day!" she wrote. "A very Happy Mother's Day to all the Mamas! ‪#MothersDay."

Judging from the smile on her face, motherhood is certainly agreeing with Nettles, and she is in love with her new role. She has taken some time off from the band to just be a mom and enjoy those critical and formative first few months with her little man.

“He’s super, super sweet," Nettles reveals to People. "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!”

Magnus' dad is Nettles' husband Justin Miller. He is the first child for both parents.
