Yates met Geldof in the early days of The Boomtown Rats. They became a couple in 1976 when she flew to Paris to surprise him while the band was playing there. Their first daughter, Fifi Trixibelle, was born on 31 March 1983, named Fifi after Geldof's aunt Fifi, and Trixibelle because Yates wanted a belle in the family. After ten years together, they married on 31 August 1986 in Las Vegas, with Simon Le Bon of Duran Duran acting as best man. The couple then had two more daughters, Peaches Geldof on 13 March 1989, and Pixie Geldof on 17 September 1990.
