We can't say we were expecting this, um, musical collaboration, but we're strangely intrigued.
Yes, those animated rodents who famously brought us a helium-voiced rendition of Beyonce's "Single Ladies (Put a Ring on It)" in their 2009 "squeakquel" have taken on another giant of the music industry: Lady Gaga.
Along with their Chipettes, Alvin (Justin Long), Simon (Matthew Gray Gubler) and Theodore (Jesse McCartney) shake their furry tushes and flex their high-pitched vocal chords to Gaga's "Bad Romance", as well as an equally ear-splitting version of Willow Smith's "Whip My Hair".
So do they do Gaga justice? Watch the trailer above for their new movie Alvin and the Chipmunks: Chipwrecked and tell us what you think below.
Chipmunk fans, this movie's out January 1, 2012.
