Tennis star Serena Williams is officially back on the tennis court, and once again, it's her outfit that's getting most of the attention.

Williams, who was hospitalized in February because of a pulmonary embolism (blood clot in the lungs), posted a photo of herself on the practice court Tuesday, wearing a full-length hot pink body suit.

"Look who I spotted on the court," the caption read. "Her first day back."

The photo was posted on her Twitter account.

Williams' agent, Jill Smoller, confirmed the news to the NY Times, saying, "She was just hitting serves and hitting the ball around. She's doing more and more every day and feeling good. That's the message. Everything is progressing nicely."

Williams is known for her outrageous tennis outfits, but this one may take the cake. See the full-sized image below.
