She's no stranger to performing in front of millions of fans.

Fresh off her national anthem performance at the Super Bowl, Alicia Keys showed off her toned tummy as she rocked the Toyota Center for the half-time show at the NBA All-Star game in Houston, Texas on Sunday.

The superstar, who gave birth to her son Egypt in 2010, bared her taught midriff in a black sequinned crop top and high-waisted leather sweatpants.

The 32-year-old singer opened up her performance sitting behind a piano while a video tribute to New York City served as a backdrop to her song Empire State of Mind.

A gaggle of female dancers stepped out on the stage, which had a changing LED-screen viewable to the audience in the highest rafters.

The medley continued, transforming into a reggae version of her latest hit, Girl on Fire.

The biggest names hitting the court included Kobe Bryant, Dwight Howard and Blake Griffin playing for the West against the East's Dwayne Wade, LeBron James and Carmelo Anthony.

Unfortunately for Alicia, who hails from New York, the East was bested by Kobe and his teammates, who carried home a 148-138 victory.

The game came as the cap off to the All-star weekend, which also featured a celebrity game on Saturday and performances on that evening by American Idol Phillip Phillips and Ellie Goulding.
