Nicole Scherzinger feels "fireworks" when she's in love.

The singer has been in an on/off relationship with Formula 1 star Lewis Hamilton since 2007. They split up in July last year, but it's thought they decided to give things another go in 2014.

Nicole's latest single Your Love is all about that special feeling, which inspired the star to open up about how relationships affect her.

"Love makes me feel like... it's just that unexplainable feeling that love makes you feel," she grinned to UK TV show Good Morning Britain. "It's just like 'ahhhh'. Like everything; fireworks and all that yummy, gushy stuff."

Nicole's song will be released on July 13 and she's been working hard on the accompanying video, which premiered earlier this week. To prepare, she's been getting in tune with her inner self.

"It's deep; I've been getting into yoga," she divulged.

"I'm embracing it. This is my fantasy-dream sequence."

Nicole, 35, and 29-year-old Lewis seem to be getting on better than ever and were snapped looking cosy during Cannes Film Festival and while in Monaco for the Grand Prix.

Earlier this year, there was speculation Lewis had popped the question to Nicole.

Their split is in part thought to have been due to the sports star's reluctance to settle down, something Nicole is said to crave.

However, he denied that they would be walking down the aisle anytime soon.

"Hey all, need to talk about these rumors. I thought I should let you guys know that I haven't proposed to Nicole. (sic)" Lewis clarified on Twitter in March.
