Demi Lovato and Iggy Azalea are some serious BFFs.

Not only is the "Cool For The Summer" singer going to be a bridesmaid in Iggy's upcoming wedding, but the two are going to team up for Demi's album.

“I am so excited not only to be one of her bridesmaids, she’s one of my closest friends and it would be an honor to have her on my album," Demi told Ryan Seacrest. "So, I’m trying to figure out which song right now, actually, to put her on. But it will definitely happen.”

Demi, who is gearing up to show off her "badass" side on her fifth album, revealed that they would be recording the song before Iggy walks down the aisle to wed fiancé Nick Young. Demi was on-hand when the NBA player got down on one knee to propose to his longtime girlfriend at an amusement park back in June.

“Nick is a little crazy. The way that he proposed was he got down on one knee and was like, ’Will you rock with me?'” Demi recently said. “And she’s like ’You have to ask the question. That’s not how you ask it.’ So he was like ’Will you marry me?’ and she’s like ’Yeah.’ He’s a clown and she’s hilarious and seeing the two of them together is really funny, so I can’t imagine what the wedding is going to be like.”
