While discussing some of his past music videos, 30-year-old Kelly admitted that the one for “Bloody Valentine” has become his favorite because of his co-star, girlfriend Megan Fox, and her feet.

“I said ‘Sail’ was my favorite music video, but for other more personal reasons ‘Bloody Valentine’ might now be my favorite video,” he explained in a video for Teen Vogue.

“It’s no secret I think feet are beautiful, and I think Megan has the most beautiful feet that exist,” he continued. “…I was like ‘Megan, you already know what I’m about to ask you.’ She was like, ‘Yeah, I literally got a pedicure just because I knew you were going to ask me that.’

“So I was like, ‘Alright, well plop it on.’”

In the “Bloody Valentine” video, Fox steps her chipped red-pedicured foot onto Kelly’s duct-taped face.

Since splitting from husband Brian Austin Green, Fox, 34, hasn’t concealed her romance with Kelly. The two packed on the PDA at the airport and posted videos from their romantic sushi picnic where Kelly declared he was “in love.”
