Matthew McConaughey and Camila Alves were glowing on the red carpet in Austin yesterday. The couple posed for pictures on their way into ACL Live at The Moody Theater, where Matthew, in his blue suede shoes, introduced a performance by John Mellencamp. The gala concert was part of a two-day charity event, which continues today, put on by the Mack, Jack & McConaughey foundation. Matthew and Camila teamed up with University of Texas head football coach Mack Brown and his wife, Sally, and singer Jack Ingram and his wife, Amy, to create the organization, which supports programs for underserved children. The event was the group's first fundraising effort since joining together late last year, and they'll be back in the spotlight today with a Celebrity Classic Golf Tournament and at a special Lela Rose fashion show at Neiman Marcus.
