Former world no. 1 Serena Williams beleives she has plenty of options when it comes to mixed doubles partners for the Londoon Olympic Games.

Serena had said she would play with good friend Andy Roddick but at the Fed Cup over the weekend she said she is spolit for choice.

"A girl loves to have choices," she said. "Obviously the Bryans are like the world's best doubles players. Andy [Roddick] and I are super, super close. Personally I love John [Isner]. You're not going to break the guy. It's an automatic I-don't-know-how-many games. I think it's so hard to choose. I don't know if you just throw everyone's name in a hat and figure out what happens next. Regardless, we want to do really well and take home a medal for the country. That's what it's all about."
