Sophia Umansky is opening up about a very embarrassing experience. "At Alexia's wedding, as we were leaving the party to go back to the house that we were staying at," Umansky, 25, said in a video shared via TikTok on Thursday, September 18, of her sister's September 6 wedding. "I turned to my friend and I was like, 'This is so weird. I know for a fact I had underwear on and I don't have it on anymore. I know what a free vagine feels like. It's just not on me anymore.' And she was like, 'You definitely still have it on you. It didn't fall off and disappear.
