Nicole Scherzinger and her boyfriend Lewis Hamilton have been dating on and off for six years now, and fans can't wait for the couple to get engaged. Nicole Scherzinger was spotted on a beach in Malibu in what looks like a wedding dress, shooting a new music video. Is Nicole Scherzinger hinting at her hopes to become engaged to boyfriend Lewis Hamilton?

"Got to set early this morning to get my head in the game for my new #musicvideo ," the former "X Factor" judge wrote on Twitter, before posting a picture of her solo yoga session on the beach, Capital FM reports.

Lewis Hamilton's girlfriend wore "bridal inspired looks" while shooting her new music video on the beach in Malibu, according to The Daily Mail. Nicole Scherzinger wore a white and blue dress with a long chiffon train, and later changed into a white lace corset underneath a sheer matching dress as she writhed around in the sand and perched herself atop a log for sexy shots.

She later posted a short behind-the-scenes video on Instagram with the message: "Beautiful day on the beach! On the set of my new music video for my first single... #comingsoon"

Though we can't confirm that Nicole was going for a wedding dress feel to her music video, we have to admit that the white lace, chiffon, and long train to her outfits make us hear wedding bells in our heads, especially following rumors that she and boyfriend Lewis Hamilton are getting closer and stronger in their relationship.

However, Lewis recently took to Twitter to debunk rumors of their engagement. Though Nicole and Lewis are back together after their 2013 break up, the couple are not engaged.

"Hey all, need to talk about these rumours. I thought I should let you guys know that I haven't proposed to Nicole," Lewis wrote on Twitter on March 17.

Nicole Scherzinger was also spotted at LAX International Airport after a flight from London, England on March 19, and she wasn't wearing a wedding ring on her left hand.

The former Pussycat Doll, 35, and her British Formula One racer boyfriend, 29, have dated on and off for almost six years. They broke up and got back together in 2010, and then split again in summer 2013. They were rumored to have rekindled their romance last December over the holiday season.
