For two special One Direction fans, the band's Atlanta concert on Wednesday, Oct. 1, was truly the best show ever. 

A man named Bradley Chisenhall made the evening one to remember for his girlfriend, Christine Kozlowski. Days before the boys of One Direction took the stage at Atlanta's Georgia Dome, Chisenhall began campaigning the band to let him propose during the concert. 

"Help me propose to my girlfriend tomorrow night at the show," he tweeted repeatedly at the band, getting One Direction fan accounts in on the promotion of his request. Chisenhall's plan gained enough momentum that it commanded the attention of the "Best Song Ever" performers. 

In the middle of the Southern show, 1D heartthrob Harry Styles took a mic and paced the stage. "I have a friend here with us tonight," he told the crowd. "He's called Bradley."

"Here he is!" Styles exclaimed as he found the young man. As the cameras panned to the fan and his girlfriend, Styles questioned, "Would you like to bring your girlfriend up this way?"

Chisenhall then got down on one knee, presenting a ring and a marriage proposal to his beauty queen love Kozlowski, who was Miss Mississippi 2008. She quickly said yes, accepting the ring and jumping up to hug her fiancé. 

"Insane," the newly engaged Kozlowski tweeted after the show. "Best b-day  ever. can't even deal. Thanks to all for our sweet congrats and helping." 

Chisenhall chimed in as well, tweeting, "Thanks for the help directioners!!! Y'all made this night amazing! Harry was so awesome! Thanks again!"
