Justin Timberlake dined at Dominick's restaurant with a few friends last night, and not only did the former boy bander enjoy an expensive meal, but his seemingly casual outfit cost thousands of dollars!

Justin wore a $4,600 quilted Louis Vuitton jacket, and he rocked a J. Lindeberg logo hoodie under his fancy winter coat. The brand's sweatshirts are generally priced at $170 and up, and when you factor in the Nike kicks, glasses and other accessories, that's more money than the average American makes in a month!

And the jeans aren't JT's own line, William Rast ... so what gives?

And what gives with Jessica Biel? Are these two together or not??? Apparently Justin doesn't want us to know ...
