The couple exchanged vows in front of family and friends at the Terranea Resort in Rancho Palos Verdes, Los Angeles, reported People magazine.
"We can't wait to start our life together. We're looking forward to just being each others' best friend," Ne-Yo said.
A picture of the newlyweds revealed the bride in a pretty white gown with lace sleeves.
Ne-Yo, whose real name is Shaffer Chimere Smith, met Renay for a collaboration for his 2015 album "Non-Fiction".
He proposed to her last summer and rumours about them already married surfaced in August as they announced Renay's pregnancy. The couple are expecting a baby boy later this year.
