Matthew McConaughey has revealed he and wife Camila Alves are keeping the sex of their new baby a secret – even from themselves.

The Magic Mike star and Brazilian model Camila – who already have a daughter, two-year-old Vida, and son Levi, three – announced they are expecting their third child together, just a month after tying the knot.

Matthew revealed: “We don’t know (if it’s a boy or a girl). We didn’t find out with the first two and we won’t find out with this one.”

The 42-year-old actor plays a male stripper in Steven Soderbergh’s new film Magic Mike.

Miley Cyrus is reportedly keen to start a family with fiance Liam Hemsworth as soon as possible.

A month after announcing that she is engaged to the Hunger Games star, 22, bride-to-be Cyrus, 19, is not as worried about wedding planning as much as she is about family planning. “Miley and Liam really want to have a baby quickly,” as Cyrus family source

The pair have been together since filming The Last Song together in 2009.

Hemsworth is believed to be especially keen to start a family since his older brother Chris Hemsworth and his wife Elsa Pataky, welcomed their daughter India in May.

Cyrus and Hemsworth already have five dogs together and are likely to also receive the support of both their families when they expand their crew to include a baby.

“They are both mature and ready for this,” says a source of the couple. “Miley is 19 going on 40.”
