Matty Healy and Gabbriette Bechtel practiced their vows and a dramatic dip kiss during a Friday rehearsal in Hollywood. The couple later partied at Rainbow Bar & Grill after arriving in a black Rolls-Royce.
The 1975 frontman wore a black suit while Gabbriette donned a long black coat over what looked like a white gown. Video from the event showed the pair smiling as they were announced husband and wife for practice.
A source told The Sun the wedding this weekend will be far glitzier than expected, with the couple eyeing Chateau Marmont and Madonna's home as venues. Guests include Charli XCX, Nick Grimshaw and the band.
Matty's parents Denise Welch and Tim Healy flew to Los Angeles last week. The nuptials come two weeks after Taylor Swift married Travis Kelce in New York.
So... will the glitz live up to the rehearsal hype?
