Nicole Richie got harnessed and spanked on stage by Britney Spears -- and she loved every minute of it!

The "Candidly Nicole" star stopped by "The Tonight Show" with Jimmy Fallon on Monday, where the two reminisced about her cameo during Spears' "Piece of Me" show in Las Vegas.

The fashionista was pulled onto the stage and walked around like a dog on a leash during the pop star's "Freakshow" performance.

The reality star explained that she was a huge Britney fan from the time she was 15. "I'm like that with Harry Styles now," Fallon quipped.

While the experience of meeting her idol for the first time was an odd one, it didn't sway her love. "It was the greatest moment of my life," Richie revealed.

Check out what else she said in the clip above -- it’s definitely worth watching!
