NE-YO ENGAGED, EXPECTING SECOND CHILD

And baby makes four!

R&B superstar Ne-Yo is set to be a father again -- and he's engaged, too!

A rep for the "Closer" singer (real name: Shaffer Chimere Smith) tells Us Weekly that his longtime girlfriend, Atlanta boutique owner Monyetta Shaw, are engaged and expecting their second child together.

Ne-Yo, 31, became a first-time dad in November 2010, when Shaw gave birth to daughter Madilyn Grace.
