Matthew McConaughey and Camila Alves expecting   Play video

Matthew McConaughey is preparing to welcome another baby into his brood - his new wife Camila Alves is expecting the couple's third child.

The Magic Mike hunk and the Brazilian beauty walked down the aisle together last month, and it's now emerged the blushing bride was hiding a small baby bump under her wedding dress.

Announcing the happy news on America's Independence Day, McConaughey took to his Twitter.com page to write, "happy birthday America, more good news, Camila and I are expecting our 3rd child, God bless, just keep livin."

Before their wedding, Alves revealed that they had decided to exchange vows for the sake of their kids - son Levi, three, and daughter Vida, two - so that the whole family shared the same last name.

She said, "I think it's great for the kids. Levi actually understands what it means now that Mama's going to have the same last name as they have, so that's neat."
