Charli XCX may have traded her “brat” title for “bride” … ’cause she was photographed in a wedding dress standing alongside her man, George Daniel!

The pop star was filmed along with the 1975 drummer outside Hackney Town Hall in London … stunning in a white, strapless wedding dress.

They’re posing for shots with family members … and, for all intents and purposes, it looks like they’ve just gotten hitched! We’ve reached out to their reps to confirm.

Reports have been coming out detailing when and where these nuptials might take place … but, it still comes as a bit of a shock — ’cause these two kept this all under wraps.
