Matthew McConaughey's mum has claimed that the actor's dad died during sexual intercourse.

Kay McConaughey, 77, wrote about the incident in her new book I Amaze Myself!.

Speaking to Us magazine, Kay said: "On Monday mornings, he and I often said goodbye by making love. But one day, all of a sudden, it just happened.

"I knew that something was wrong, because I didn't hear anything from him. Just nothing. But it was just the best way to go!"

When her husband was taken away from the house afterwards, Key said that she ensured he wasn't wearing any clothes so people could admire his manhood.

She commented: "I was just so proud to show off my big old Jim McConaughey - and his gift."
