Serena Williams Flashes Her Butt In Sexy Swimsuit As She Hangs Out With Colton Haynes

Serena Williams looked happier than ever as she enjoyed some downtime with two close friends in San Marcos, Texas, over the weekend.

The tennis ace was joined by TV star Colton Haynes and another girlfriend as they enjoyed a break at the natural springs - complete with huge rubber rings.

Serena, who is rumored to be dating rapper Drake, cheekily flashed her curves to camera in a bright orange swimsuit as she held onto her red rubber ring, while topless Colton was flexing his muscles as he posed for the snap.
