The tennis ace who announced last month she's expecting her first child, spent a fun time Wednesday at Disney World's new Pandora - World of Avatar attraction in Orlando, Florida.

She shared a photo to Instagram showing herself in a headdress and holding up a torch from the James Cameron-created universe.

'Had the best time at Disney, Pandora was unreal!!' she wrote alongside the snap in which she's wearing denim overall shorts with a black t-shirt and black trainers.

Of course, Serena was given a VIP sneak peek at the theme park attraction that won't open to the public until May 27.

Disney is in full promotional mode as it bets half a billion dollars on the public flocking to see the high-tech 12-acre land at its Animal Kingdom theme park.
