Matthew McConaughey

The ‘Failure to Launch’ star, 53, refuses to wear deodorant as he prefers to be au naturel.

Yvette Nicole Brown - his co-star on 'Tropic Thunder’ - revealed that Matt has achieved his own unique scent due to his lack of anti-perspirant.

Appearing on ‘The Jess Cagle Podcast’, Yvette said: "He smells like granola and good living."
