Celebrities were at their fashionable best at the 15th annual BET Awards, held at the Microsoft Theater in Los Angeles on 28 June.

Chris Brown's former girlfriend, Karrueche Tran went for a bold look and wore a revealing bralet on the red carpet. The 27-year-old also turned heads by dying her hair grey.

Nicki Minaj, who won two awards at the event -- Best Female Hip-Hop Artist and the Viewer's Choice Award for her song Only -- wore a black dress, with a large zip on it.

Tyga's former fiancee Blac Chyna and hip hop artist Amber Rose, came as a couple to the event, and wore matching white suits.

"We decided to come together and celebrate the fact that in all 50 states gay marriage is legal," Rose said. "And we support the gay and lesbian community so much we decided to be each other's date today."

Meanwhile, at the event, Janet Jackson received the Ultimate Icon: Music Dance Visual Award, while Smokey Robinson was honoured with the Lifetime Achievement Award and Tom Joyner the Humanitarian Award.

The show was hosted by Anthony Anderson and Tracee Ellis Ross.
