Andy Roddick and Serena Williams hope to team up for the United States in mixed doubles when the event returns to the Olympics at the 2012 London Games.

Roddick, 27, the men’s world number seven, has had discussions with Williams, 28, the women’s number one.

And Roddick said on Twitter: “It’s confirmed! Serena and Andy teaming up for mixed doubles at 2012 games if they push the mixed doubles through.”

The tennis events at London 2012 will take place on Wimbledon’s grass courts.

The International Olympic Committe announced last week that mixed doubles would be introduced to the Olympic programme in time for 2012.

But Roddick and Serena could face competition to represent the US from doubles star Bob Bryan, who hopes to form a pairing with Serena’s elder sister Venus, 29.

Bryan, 31, who has won seven Grand Slam doubles titles, and six Grand Slam mixed doubles titles, said on Twitter: “It’s not confirmed yet but if Bob and Venus play in 2012 we’ll smoke Andy and Serena.”(source)
