Could Harry Styles be engaged? The One Direction group member got a little spontaneous and proposed to a fan the other night while performing during one of his show in Philadelphia.

The 20-year-old singer couldn't help but pop the question to a fan in the crowd who was definitely dressed for the occasion.

According to E! News, the 1D member noticed a fan in the crowd wearing a wedding dress and asked for the female's hand in marriage. The lucky fan was named Priya Thakker who shared the Vine video of the mock proposal on Twitter.

Attached to the video of the memorable moment for the excited fan was the caption, "JUST WATCH THIS VINE OF ME GETTING TO PROPOSED TO BY HARRY STYLES AND REJOICE WITH ME PLEASE KUST DO IT."

In the clip, Styles takes a break from singing during the "Where We Are" tour to say, "Priya, will you marry me?" Following the fake proposal, the crowd erupts into screams, cheers and clapping.

Thakker has been gushing about the once-in-a-lifetime moment over social media all week. She tweeted, "I wore a wedding dress to a 1D concert and Harry proposed to me thats all."

Priya went on to add, "I'm probably never going to sleep again to be honest. I just keep replaying 'Priya will you marry me?' in my head IN HIS BRITISH ACCENT OMG."

The excited fan later posted, "Remember when Harry said 'I almost wore my wedding dress...that coulda been awkward.'"

When Harry Styles isn't proposing marriage to fans the heartthrob is busy rekindling romances with ex-girlfriends.

The One Direction singer was spotted with model ex-girlfriend Paige Reifler at London's Shoreditch House enjoying a fun night out last month.

A source told The Sun, "Harry turned up specifically to meet up with Paige but they were as discreet as possible at the event.

"Then they both left the main party, which was on the rooftop next to the pool, and went downstairs to the more private restaurant."

Although Harry Styles and Paige Reifler are trying to make things work, insiders close to the two said it will be difficult for the couple to resume a serious relationship because they both have busy schedules.
