Justin Bieber risked a seriously embarrassing wardrobe malfunction yesterday.
The Sorry singer took a break from his Purpose World Tour as he hit the waves wearing just his white Calvin Klein briefs.
The 22-year-old star was partying with his pals, including Pretty Little Liars star Ashley Benson, when he decided to impress them with his wakeboarding skills.
Clearly failing to find any suitable trunks, Justin had no qualms about stripping down to his undies and showing off his muscular physique. See more photos below…
