HP has announced Serena Williams as the latest celebrity to take part in its "The Computer is Personal Again" ad campaign just in time for the US Open.

The series previously featured Jay-Z, Vera Wang, Pharell and Shaun White and has generated some buzz for showcasing headless celebrities talking about what they do on their computers. Last time we saw Williams around gadgets she was "making news" clutching her limited edition Dwayne Wade Sidekick, so this ad is a real upgrade. I'm a mac girl through and through, but I can't help but be mesmerized by the playful and colorful graphics. Or maybe it's just her biceps.
