Is He Interested in the Clothes or the Car?

Now, Nick Lachey doing Miller Lite commercials - that I would understand. How many times did he drink it during Newlyweds and how many times do the paps snap him buying it at his local grocery store?

But this caught me by surprise. People reports that Lachey walked the runway "in Dolce & Gabbana at the GM Style event in Detroit on Saturday." His girlfriend Vanessa Minnillo was right there to watch him!
