One Direction star Harry Styles helps fan propose to girlfriend at concert

Best song ever? Try best proposal ever.

One Direction member Harry Styles helped a fan propose to his girlfriend at Wednesday night’s concert in Atlanta.

And it was — of course — caught on tape.

In the video footage, Styles was seen stopping the show to seek out Bradley Chisenhall, a fan who asked for his help just a day earlier.

"I have a friend in the audience tonight," Styles said. "He's called Bradley. Here he is. Bradley, would you like to bring your girlfriend up on stage?"

Well, Chisenhall didn't make it to the stage, but he did manage to "put a ring on it."

The fan got down on one knee to propose to his girlfriend Christine Kozlowski.

Kozlowski quickly said "yes" and jumped into his arms.

"She said 'yes,'" Styles screamed into the microphone.

The proposal comes after fans helped Chisenhall get the hashtag #1DProposal trending on Twitter.

“Help me get #1DProposal trending,” Chisenhall tweeted. “I'm proposing to my gf at the concert tomorrow night and I want the guys to help me out. Thank y'all!”

Chisenhall’s request was granted with nearly 2,000 retweets.

Then Chisenhall reached out directly to the group. 

“Help me propose to my girlfriend tomorrow night at the show. @Harry_Styles @Real_Liam_Payne @NiallOfficial @zaynecomecu @louis_tomlinson.”

Styles didn't disappoint.

"Thank u @Harry_Styles for making this all happen for me& @Christinekozlo &also making my sisters @Shelbymmorgann nite," Chisenhall tweeted on Wednesday along with a picture of Styles.

Kozlowsi also thanked all those who helped and showed off her new engagement ring on Twitter.

"He liked it and he put a ring on it. #1DProposal @ChisenhallAL you are & always will be my handsome Prince Charming," she tweeted.

As of Thursday, more than 750,000 people have tweeted about the #1DProposal, according to Topsy, a social media analytics firm.

Apparently fans can't get enough of One Direction — story of their lives.
