Matthew McConaughey Waits for His Scene on the Set

Finally, we figured out the secret to Matthew McConaughey's beyond perfect smile! Apparently, he likes to chew on dental floss sticks, like he was caught doing on the set of The Lincoln Lawyer in L.A. yesterday. Matt has been working on this movie all summer, and has been spotted having fun with co-stars like Marisa Tomei!

The Lincoln Lawyer is about a lawyer who has high-profile clients in Beverly Hills, but conducts all of his business out of the back of his Lincoln town car.

We still have awhile to wait to see Matthew in his latest lawyerly role — the flick is slated to be released in 2011.
