The X Factor judge said she had to turn it down because she was contracted elsewhere, reported Mirror online.
The Pussycat Dolls star also claimed that she also turned down Rihanna's Calvin Harris hit song 'We Found Love' before the Bajan beauty recorded it.
"I passed on We Found Love," Scherzinger was quoted as telling fashion and music magazine Notion.
"I got the demo of that song and I was busy at the time. They'd sent me a few dance tracks and I wasn't able to get to them and I was like, 'Oh, there's so much dance and I want to take a break from it.' That was my fault. I slept on it," she added.
