• There were bound to be a few dramatic moments at the inaugural parties last night: Sheryl Crow had an awkward run in with her ex, Kid Rock, in the lobby of Donovan House. John Legend was forced to make a last-minute stop at Bloomingdale's because his girlfriend didn't have a gown. Susan Sarandon got a reporter kicked out an event for daring to ask a question.

• One possible explanation for Lopez's late arrival: She was spotted at the Scientology Center in LA yesterday morning, trying to sneak out of the building without being noticed. [NYDN]
• Another headache for John Travolta and Kelly Preston: A politician in the Bahamas may have been part of a plot to extort money from the couple following the death of Jett Travolta. [OK!]

A longtime Upper East Side social fixture and former model, Griscom is the daughter of Elizabeth Rohatyn and wife of financier Felix Rohatyn.
