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 on Wednesday (04.07.12).

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 (09.06.12) 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''.
