During his Reddit AMA this week, Fat Mike talked about the next Me First and the Gimme Gimmes release:

New Me First and the Gimme Gimmes album just got finished last week, and the theme is Divas! We do [Barbara] Streisand, Christina Aguilera, and Lady Gaga among others. Its pretty douchey (pun intended), but good.

The band last released Sing in Japanese in 2011.
