It's official! Fergie and Josh Duhamel are engaged, and In Style helped play matchmaker: Back in 2004, Duhamel revealed to us that he had dreams about the songstress. "I can't tell you what happens, but I can tell you it involves Fergie," the Transformers star said. "I've got the biggest crush on her! God, is she hot!" When they were introduced, Fergie playfully asked the nervous Duhamel, "I read In Style. So...how was I in your dream?" Three years later, they're set to tie the knot. The happy couple haven't yet figured out wedding details, but a source close to Fergie tells People magazine that "she is the happiest girl on earth."
