On Monday, the R&B superstar and girlfriend Monyetta Shaw welcomed their second child. On Friday the “Closer” singer (real name: Shaffer Chimere Smith) announced his second child’s name — Mason Evan Smith — on Twitter.

“If you are truly fam, you’ll help me welcome the heir to my throne,” Ne-Yo tweeted. “Born Oct. 9, 6 pounds, 10 oz!”

The 31-year-old first became a dad in November 2010, when Shaw — who co-owns Emerlyn & Ester, a new boutique in Atlanta’s Buckhead district — gave birth to daughter Madilyn Grace.

Congrats to Ne-Yo and his family.
