Even in a grass skirt, Justin Timberlake looks darn sexy!

The Social Network star donned a Hawaiian Skirt, complete with matching Lei, for the Walmart Shareholders' Meeting in Fayetteville, Arkansas on Friday morning, where he performed an extra-special gig at the town's Bud Walton Arena.

During his performance the newly engaged singer joked: "It's 7:20 a.m. That's how Walmart does it? I need to work on my schedule," before leading the audience in the company's "Walmart Cheer."

Timberlake is gearing up to walk down the aisle with fiancee Jessica Biel, and the couple had a star-studded party for 100-plus friends and family last weekend to celebrate. We can't wait to see the gorgeous couple tie the knot!
