The Hills star Kristin Cavallari has recalled her most embarrassing moment.
Speaking to Us magazine, the 22-year-old recounted that the incident had happened at a photoshoot while she was on her period.
"I don't know if this is appropriate or not. I was at a photoshoot and I had to wear little booty shorts and lingerie," she explained.
"The stylist was looking at me and she was like, 'You have a string hanging from your little underwear'. She came over and pulled on my tampon string! That was a little embarrassing!"
Cavallari recently denied online reports that she earned $90,000 per episode of her MTV series.
