"There is absolutely no truth to any of the rumors," Smirnoff told Us Weekly in a Wednesday report.
Baldwin and Smirnoff were spotted together last Saturday sitting by the pool at Las Vegas' Palazzo hotel, where an onlooker described the pair as "very affectionate." They subsequently retreated to MGM to watch a boxing match before hitting the Tao nightclub.
However Baldwin denied he and Smirnoff are dating, telling Us she's an "outstanding dancer and a very sweet girl but that's about it."
Smirnoff issued a similar accolade upon Baldwin before denying a romance.
