Matthew McConaughey says his mother is a "mess" when it comes to his popularity. The actor said when he first found fame, it was difficult for him to keep his eager mother, Kay, 87, tight-lipped about his personal life.

"She's a mess, man. When I first became famous she would show up at my interviews. It wasn't about me, it was about her. "I would say, 'Please Mom - I'm trying to navigate this newfound celebrity and being in the public eye, so just watch the loose lips. Just let me be the lead voice for now...'" McConaughey told the Telegraph magazine.
