Kingston and Zuma's daddy is headed for the slammer -- and he's not even fully dressed!

In Los Angeles on Monday, a bare-chested Gavin Rossdale, clad in just boxer shorts, open silky robe and tube socks, was led away in handcuffs by a policeman.

Thankfully, the Bush frontman and hubby to Gwen Stefani isn't really in trouble with the law; he was filming a cameo as a shady club promoter in The Bling Ring.

Directed by Sofia Coppolla and starring Emma Watson, Leslie Mann, and American Horror Story star Taissa Farmiga, the flick is inspired by the real-life group of tech-savvy Hollywood-area teens who burglarized the homes of Paris Hilton, Lindsay Lohan, Orlando Bloom, Rachel Bilson and Audrina Patridge between 2008 and 2009.

It's not the first time the "Glycerine" singer, 46, has acted onscreen; he's appeared in films like Little Black Book and Constantine and such TV shows as Burn Notice and Criminal Minds.
