Los Angeles - Britney Spears has told Jimmy Fallon he can have a spanking from her "anytime".
The Perfume singer watched with amusement when her friend Nicole Richie told Jimmy during her interview on The Tonight Show on Monday that getting slapped across the butt by Britney on stage in Las Vegas was the "greatest moment" of her life.
After her revelation, Jimmy seemed very amused and impressed with the story and now Britney has extended the offer to the talk show host.
The 32-year-old pop superstar posted on Twitter: "Good girls need spankings too @nicolerichie ;) ... You've got an open invitation for one anytime @jimmyfallon (sic)"
Nicole, 32, had been dancing and singing along at one of Britney's Piece of Me
residency shows at the Planet Hollywood Resort and Casino in February when she was brought on stage and had her butt cheeks stung by whip-wielding Britney.
Recalling the moment, the fashion designer said: "I finally went to go see her in concert. I'm grooving, I'm having the best time.
"All of a sudden, her big security guard just taps me on the shoulder. He says, 'Come with me.' He pulls me up on stage ... and her dancers come over to me and whisper 'Get on all fours' ... It's just something you don't question.
"Britney Spears came out when I was 15. And this was the last time in my life that I was like a die-hard fan.
"That love never went away; when I see Britney Spears, I turn into my 15-year-old self."
