Aguilera's friends kept most of the trip's details a secret, and the singer was wowed in more ways than one. She had never been to Cabo, nor had she ever even attended a bachelorette party. "I had no idea what I was walking into," says the four-time Grammy winner of the long weekend she spent with friends at the One & Only Palmilla resort. "I was just excited to take a moment for myself to sit back and enjoy the ride. I think that's the most important thing for a bride-to-be."
