Heidi Klum has rebounded — has Seal now done the same? The "Kiss from a Rose" singer, 49, hit a star-studded Halloween party Friday night at Hollywood insider Mike Meldman’s home with a mystery blonde on his arm. Dressed as a Boston Celtic player, Seal took a pretty brunette woman wearing a purple, oversized Los Angeles Lakers Jersey and headband. Although Seal’s date has yet to be identified, she smiled broadly for the cameras. According a source, a fellow reveler asked Seal if his gal pal was a girlfriend. "No!" he replied. "We’re just friends."
