Justin and Jessica got engaged in December after the singer/actor proposed on the mountains of Jackson in Wyoming. Justin reportedly celebrated his bachelor party last September with photos of the singer partying with a bunch of his male friends surfaced on the web. They were first snapped in Las Vegas then later in Cabo San Lucas, Mexico.

Just recently, JT spilled details about how he asked Jessica for a date. The singer turned actor definitely sounded smitten while talking about his ladylove.

"I did it the old fashion way - by telephone. That's something I learned from both my stepdad and my grandfather - that there is a thing called chivalry and it doesn't have to die with the birth of the internet," he said. "The way I see it, if you're asking a girl out on a date, it's only right to do it in a way that she can hear your voice."
