Tommy Boy is on the move today. First he told us what was up this morning; now, sources close to the Hilfiger clan say the designer has moved back into his seven-bedroom backcountry Greenwich estate with his ex-wife Susie Hilfiger, creative director at Best & Co. "They're totally back together," a spy told BlackBook. "They're living together as one big happy family in Greenwich." But wait, there's more! We're also told that his former fiancé Dee Ocleppo called off the wedding because she was unhappy with the prenup deal. The wedding was scheduled to be held on the Caribbean island of Mustique in August. Meanwhile, Hilfiger has put his duplex at the Plaza on the block for $50 million.
