Matthew McConaughey's award-winning baby

Matthew McConaughey conceived his daughter after the Academy of Country Music (ACM) Awards last year.

The 'Fool's Gold' actor - who has a 21-month-old son Levi and three-month-old daughter Vida with his partner Camila Alves - revealed the story of the tot's conception to a packed audience at this year's ceremony at Las Vegas' MGM Grand hotel.

He said: "After the show last year, my lady Camila and I... went back to the hotel and conceived the little lady that is now our daughter."

However, the 40-year-old star insisted he and Camila wouldn't be marking the event in the same way again.

He joked: "I'm having a good time again but I promise you, me and Camila are not going to try and get so lucky this year. Two is enough!"

Matthew was at the ceremony to present Brad Paisley with the Top Male Vocalist honour, and the 'Water' singer mocked the actor - who starred with the musician's wife Kimberly Williams-Paisley in 2006 movie 'We Are Marshal' - by claiming to be a better kisser.

He joked: "My wife says 'hi'. She loved playing your wife in 'We Are Marshall', but she says I'm a better kisser.

"But they didn't have any kissing scenes in that movie. So I have no idea how she knows that!"
