Carrie Underwood is going to be a new mom soon.
The country singer, 31, tweeted the baby announcement on Monday, with her two dogs wearing "I'm going to be a big brother," and "I'm going to be a big sister" shirts.
She wrote: "In honor of 'Labor' Day...Ace & Penny would like to make an announcement. Their parents couldn't be happier!"
This will be the first child for Underwood and husband Mike Fisher, 34. The couple tied the knot in 2010 at the Ritz Carlton Reynolds Plantation in Georgia.
Expect to see Underwood's baby bump real soon. The American Idol alum will once again co-host the Country Music Association Awards with Brad Paisley this November.
