The America's Got Talent judge later marked the occasion with a sweet Instagram post of her and her new husband, captioning the photo simply, "[heart emoji] 05.07.25."

The couple exchanged vows inside the historic Crypt of St. Paul's Cathedral, the same iconic church where Princess Diana wed Prince Charles, a rare honor granted to Mel B after she was awarded an MBE in 2022 for her advocacy work around domestic violence, People reported.
