Congratulations to Kelly Clarkson and hubby Brandon Blackstock, who are expecting their first child, and they couldn't be happier!

Kelly made the announcement on Twitter today:

 

Clarkson has not hidden her desire to start a family, even telling Jay Leno, "We are not announcing anything right now! ... Practice makes perfect! We're trying, trying, trying … like rabbits!"

The couple tied the knot last month on OCt. 20 at Blackberry Farms in Tennessee. Blackstock has two children from a previous marriage.

Congrats!
