Clarkson, 31 — who helps look after her husband Brandon Blackstock's two children — is expecting their first child together, she announced Tuesday.
"I'm pregnant!!! Brandon and I are so excited! Best early Christmas present ever," the singer Tweets.
The big news comes a month after she and Blackstock tied the knot in an intimate ceremony in Tennessee.
