Matthew Mcconaughey has welcomed another child into the world, after his wife Camila Alves popped out baby number 3 earlier today (Dec 29).

According to TMZ, who first reported the news this morning, the Magic Mike actor stood by his wife as she gave birth in the early hours of the day at a hospital in Austin, Texas. A source close to the actor told the website that Matthew was clearly happy in regards to the impending birth, and added a few pounds to his delicately thin frame in anticipation for the arrival.

In July this year, McConaughey first announced the good news through Twitter, writing: "Happy birthday America, more good news, Camila and I are expecting our 3rd child." And now the special day has arrived, although the news has been kept under wraps for know it is believed that the little one is in fact a baby girl. This tops off quite the year for the couple, who tied the knot in June after six years together. The couple have two other children together, Levi, 4, and Vida, 2.

We at Contact Music would like to wish Matthew and Camila all the best with their latest addition to the family and the new year.
