Run, Matthew, Run!

Hunky Matthew McConaughey was spotted taking a little Saturday morning run in Malibu. The laid-back actor and dad-to-be - his Brazilian model girlfriend Camila Alves is expecting - waved to photographers as he got his cardio on, looking color-coordinated in a t-shirt and matching headband. I can't believe Matthew's actually wearing a shirt - I wonder if he ever worries about nipple chafing?
