Kelly Clarkson's such an ally to the LGBT community she helped one gay fan propose to his boyfriend in Las Vegas.

On Tuesday, Alex Malerba and Justin Blake were at the Venetian in Las Vegas to see Clarkson perform. At a photo op wit the star, Malerba dropped to one knee and popped the question.

“Asking the love of my life to marry me in front of the one and only @kellyclarkson was an amazing moment!!!! HE SAID YES,” Malerba posted on Instagram.

Clarkson was almost as excited as the couple.

“Oh my God, [I’m] so happy. Oh my God!” Clarkson gushed. “That was so beautiful, congratulations! He was like, ‘I wanna propose to him.’ I was like, ‘Come back here!'”

When the guys revealed they've been dating for four years, the "Miss Independent" singer joked, “It's about damn time—sh*t or get off the pot!"
