Courtesy of some Adidas tracksuits, matching caps and faux tashes, Anne Hathaway, Kristen Stewart and Brie Larson are transformed into guys for their pal Jenny Lewis' first music video in six years.
The trio start of playing backing band for the singer's track Just One Of The Guys, kitted out in matching white suits. Then there's some impressive lip-syncing to the track, before we see their manly(ish) makeovers.
Anne is totally hilarious in her guy guise; stroking her tash, break dancing (well - trying to, anyway) and head-banging along to the song.
But Brie and Kristen make pretty awesome bros, too, with some floppy hair to rival Justin Bieber's signature cut.
The lyrics to the song are actually pretty sad stuff about ticking biological clocks and feeling low about being baby-less, but we promise it won't fail to rouse a smile thanks to Anne, Kristen, Brie and Jenny's goofy performances.
