Nick Cannon showed off his wedding band in NYC Thursday.

The 27-year-old rapper/actor, who wed Mariah Carey last week in a secret ceremony in the Bahamas, let the world catch a glimpse of the bling as he left his hotel.

Carey, 38, and Cannon tied the knot April 30.

Before their wedding, Carey had the words "Mrs. Cannon" tattooed on her back, Oprah Winfrey said Wednesday.

The singer is scheduled to perform at Time magazine's "Time 100" party Thursday night in NYC.
