R&B crooner John Legend returns with a smooth tune featuring the boss man himself, Rick Ross. The shimmering ballad 'Who Do We Think We Are' is the first single from the singer's fourth effort, 'Love in the Future.'

The first thing you notice about the song is that it samples Jean Knight's 'Mr. Big Stuff,' which Heavy D used on his 1987 debut single of the same name. The tune also reunites Legend and Rozay again after their 2009 collaborative effort 'Magnificent.'

On the song, Legend sings about his adoration for his ladylove while Ross spits materialistic rhymes. A video for the single has already been shot in New York earlier this month and will premiere in April.

"I’m so excited to release this project. I’ve thoroughly enjoyed making this album with a team of incredibly gifted producers and co-writers,” said Legend about his new album. "Every day we went to the studio with the goal to create something beautiful, to make the best album of my career."

John Legend's album, 'Love in the Future,' is scheduled to arrive in stores on June 25.
