WATCH: Nick Jonas and the story of his embarassing boner

Cape Town – Nick Jonas got candid about the time he got a NARB (No Apparent Reason Boner) on the red carpet at the 2014 Young Hollywood Awards.

The 23-year-old told Jimmy Fallon the embarrassing story on The Tonight Show, and this is how it goes…

 “I was celebrating my last release a year-and-a-half ago, maybe two years ago, and I decided to go out with some of my friends. And one of my friends’ wives said: ‘I’ve got this weed lollipop, do you want to give it a try?’

“I thought sure why not. I never do this but I did it. I enjoyed the night and felt great, went to bed feeling fine.

“I woke up the next morning and everything was in slow motion and I’m like 'oh no! This is happening'. This is real, because I had to be up to present at the Young Hollywood Awards…"

Skip through another nap, a shower, the help of his girlfriend at the time and Nick found himself dressed and ready for the show…

“I get in the car. I’m trying to focus and get in the right mind frame. I’m feeling better and then out of nowhere I get a NARB!

“All men get a NARB from time to time. It’s just there and I didn’t know what to do!"
