ANDY GETS RANDY

Watch what happens when Andy Cohen has a lively night out. Partygoers at Space Ibiza nightclub in Hell’s Kitchen applauded the Bravo host’s moves on Saturday when Cohen (above) and a pal got flirty with a “younger man” who appeared to enjoy the attention. “First, Andy was getting flirty with the guy. Then his friend was,” reports our night owl. “People were watching, like, ‘hmmm,’ ” dished our spywitness, who says in all appeared to be in good fun. “Everybody was having a good time,” we’re told.
