Nicole Scherzinger has broken her silence after a sex tape of her and ex Lewis Hamilton was leaked online.

The two and a half minute clip of the pair in bed kissing and cuddling has been shared over 600,000 times since its hurtful leak.

Speaking at Elton John’s Oscars party in LA, she told The Sun on Sunday: “It’s been horrible.

“I genuinely don’t understand why someone would do something like this, or why they would leak it. It’s an unbelievably mean thing to do.”

A source added: “Nicole and Lewis were both horrified at the breach, and want to get to the bottom of it

“They want to know how the hell it got leaked.

Formula 1 ace Lewis, 34, and X Factor judge Nicole dated on and off for seven years before splitting in 2015.

"It's not been easy - she lives in LA, I live in Monaco and I'm travelling a lot for work," Lewis once said of their tumultuous romance, which kicked off in 2009.

"Her job is shifting all the time, whether it's X Factor or Dancing With The Stars or Cats or music," he continued.

"Juggling your schedule to meet with the other is very hard, and it's a long year with F1. At one point, I flew to Asia for five weeks and couldn't see her. It's been tough."

But despite the distance, the couple seemingly knew how to make the most of their limited time together.

Whilst filming the X Factor in 2012, Nicole reportedly arrived a day late for the judges houses in Dubai after begging bosses to let her make a saucy pit stop in London.

“The smile on her face said it had been worth it," a source cheekily told People at the time. “She must have been exhausted.”
