Never one to keep his personal hygiene to himself, Matthew McConaughey was happy to brush his chompers outside his Malibu trailer this week. His new girlfriend, Camila Alves, was nowhere to be seen, but after seeing how much she loves trailer duties, I can't imagine she was too far away. Former Sexiest Man of the Year MM was named one of People's 50 Most Beautiful People again this year (slight downgrade, but still quite the compliment), and he wasn't ashamed to admit that his rigorous work out regimen is a combination of wanting to feel good and plain old vanity. Can't blame him too much, since being vain is a given in H'wood. Plus, he's certainly got a body worth being proud of. Yowza!
