AceShowbiz - Adrien Brody and "Mad Men" star January Jones have sparked speculation they are dating, after the couple was spotted enjoying a romantic night out together in New York. The Oscar winner and the actress spent an evening in each other's company recently at the Big Apple's Rose bar - and onlookers report the pair were flirting with each other.

An eyewitness tells America's Life & Style magazine, "They held hands in full view of everyone." Jones was linked to "Entourage" star Jeremy Piven at the beginning of the year, while Brody split from Spanish actress Elsa Pataky last May.

Professionally, Adrien Brody is waiting for the release of his new film "Predators" which will hit U.S. theaters on July 9. Meanwhile, January Jones will appear in 2011 "The Hungry Rabbit Jumps" which also stars Nicolas Cage.
