A former New Jersey Net dancer thought she was moving on up with a $2 million wedding all planned out with former Nets' star Richard Jefferson, set for last weekend at Mandarin Oriental in Columbus Circle. But RJ's engagement ring turned out to be a give-and-go when Jefferson told Kesha Ni'Cole Nichols in the days leading up the wedding that he would not be attending. That didn't stop Nichols from going ahead with spending her canceled wedding night in the Mandarin, where they upgraded her to a suite with a king-sized bed and a view of the park. But not only was the bride-not-to-be at the hotel, so were "(Jefferson's) boys" who claim they found out about the change of plans hours before, but apparently were already set with using his Black Amex card for the night. The Post says that according to friends, Nichols was "not entirely caught off-guard" and "just wants to keep this as quiet as possible and move on." Jefferson recently moved on up himself to San Antonio, where he joined the Spurs in a trade for Bruce Bowen.
