Amber Riley has really been branching out since her character Mercedes graduated on Glee. First, she made her New York stage debut in the Off-Broadway revue Cotton Club Parade. Now, she's lending her voice to singer-songwriter Eric Bellinger's single "Never Be Lonely." The track, which is a take on Janet Jackson's 1998 smash "I Get Lonely," finds the duo trading soulful verses about love and neglect as Eric brings the sexy in nothing but a towel and Amber radiates emotional realness while looking through a rain-covered window. "Never Be Lonely" can be found on Eric's mixtape In the Meantime, which is available for free download here. His upcoming project, Born To Sing Vol. III, will be available April 15th. And, of course, we're still waiting to hear when we'll be getting that highly anticipated Amber Riley solo album.
