R&B superstar Ne-Yo sure has something to sing about: His girlfriend, Monyetta Shaw, welcomed their second child on Monday.

The child's gender and name have yet to be released.

Ne-Yo, 31, became a first-time dad in November 2010, when Shaw -- who co-owns with her beau Emerlyn & Ester, a new boutique in Atlanta's Buckhead district -- gave birth to daughter Madilyn Grace.

The "Closer" singer (real name: Shaffer Chimere Smith) says fatherhood has been a welcome change.

"Feels like I'm in luv for the first time," he Tweeted after his daughter was born. "Welcoming that lil' girl to the world last night defined for me what 'willing to kill and die for' truly means. My world, my life, all hers."
