Karina Smirnoff almost had a wardrobe malfunction while playing around on a Pogo Stick at a party last week.
The almost-slip happened at the opening of the C. Wonder store at the Time Warner Center, where "she was jumping up and down having so much fun there was almost a wardrobe malfunction," a witness told us.
"She said, 'Oh my God - I think my pasties just flew off!" the spy added.
Kelly Rutherford also hit up the party.
