A few days ago, Laura Jane Grace posted a photo of her band, Against Me!, and pop songstress Miley Cyrus (check it out in the Instagram shot above). It was captured following an outdoor concert from the rockers, which was recorded by Cyrus and will benefit charity.

Apparently Grace and Cyrus became fast friends over their shared interest and advocacy work to combat teenage homelessness. In the Instagram post, Grace tags Happy Hippie, Cyrus’ foundation, which works specifically in the prevention of youth homelessness.

Though there's only confirmation that the collaboration goes as far as Cyrus recording Against Me!'s backyard concert, the rumor mill is now wondering if Cyrus and the Florida rockers will record together sometime soon.

While we’ll have to continue speculating a Grace-Cyrus collab, we do know that Against Me! recently kicked off a tour in support of their most recent album, Transgender Dysphoria Blues, which arrived last year. The short jaunt continues tomorrow (Feb. 17) in Pensacola, Fla., followed by stops in Tampa, Orlando and Fort Lauderdale. Check out details here.

Back in November, the Against Me! frontwoman wrapped up her AOL web series, True Trans With Laura Jane Grace, which documented her transition as a transgender woman.
