Serena WilliamsSerena Williams' sported a wild look for her first day back on the courts.

Williams, long known for her bold style on and off the court, was back in action this week -- in full regalia.

In her first session after an 8-month injury-related hiatus, the powerhouse athlete sported a full-length, neon-pink lycra bodysuit.

She showed it off, twitpic-ing her latest style with the text, "Look who I spotted on the court. Her first day back . . . "

Perhaps Williams was feeling electric on her long-awaited return to work. She started training Tuesday in Palm Beach Gardens after a break following emergency treatment for a pulmonary embolism in February.

Prior to that, she had been out of commission since July due to tendon surgery when she lacerated her foot on some glass at a restaurant in Germany.
