(CNN) -

Maybe there's something in the water: two Hollywood couples were celebrating baby news along with Independence Day on July 4.

"Magic Mike" star Matthew McConaughey and Camila Alves, who just tied the knot in June, revealed Wednesday that they're expecting baby No. 3.

McConaughey, 42, tweeted, "happy birthday America, more good news, Camila and I are expecting our 3rd child, God bless, just keep livin."

The pair are also parents to daughter Vida, 2, as well as son Levi, who turns 4 this week.

Meanwhile, Claire Danes and husband Hugh Dancy are also getting ready for parenthood, as the two actors are expecting their first child together.

A rep for the 33-year-old "Homeland" actress confirmed the good news to People magazine. A rep involved with production on Showtime's hit series also had some good news for fans: Danes' pregnancy isn't expected to impact work on season 2, which bows on Showtime Sept. 30.
