Tennis superstars Venus and Serena Williams share a laugh during a press conference today (Dec 2) to promote Saturday’s exhibition match against Italy’s Flavia Pennetta and Francesca Schiavone in Milan, Italy.

“We’re the defending champion and we want to defend our title and I don’t see why we wouldn’t,” Serena said, of the match. “This is a good preview to the Olympics, we both want to play. So this is a great, great time for us, so exciting.”

After the event, the sisters had a blast as they indulge in some retail therapy at the Armani store. “Had a great day in Milan with Mr. Armani. . . And at Armani. Giorigo sure knows how to spoil me. Love u babes!” Serena tweeted
