Matthew McConaughey and Camila Alves are expecting their third child together.
The Magic Mike star and his model wife announced there would be a further addition to the family via his twitter page.
He wrote: "Happy birthday America, more good news, Camila and I are expecting our 3rd child, God bless, just keep livin."
Matthew and Camila married only one month ago at their home in Texas, United States.
The 42-year-old actor's 29-year-old spouse tweeted the same message just 20 minutes before her partner did.
The couple are already parents to two-year-old daughter Vida, and almost-four-year-old son Levi.
When asked on their wedding weekend about their dreams for the future, the couple told People magazine: "More of the same — and more family."
Matthew recently said he "didn't like" his latest crime thriller movie 'Killer Joe' and it made him want to "clean himself with a steel-brush".
The 'How to Lose a Guy in 10 Days' actor admitted the crime thriller - which contains suggestions of incest and a lot of nudity - was a far reach from his romantic-comedy past and made him feel "sick".
