Sarah Palin is about to become a grandmother again — times two. The 2008 GOP vice presidential candidate's daughter, Willow, is pregnant with twins.

Palin's 24-year-old daughter announced in a Monday night Instagram post that "two little babies" were coming this winter:

Palin, 55, responded to her daughter's post, writing she was "ecstatic" and "blessed."

Willow Palin tied the knot with her husband, Ricky Bailey, last year.

The upcoming bundles of joy won't be the first grandchildren for the former Alaska governor and mom of five. Palin's eldest daughter, Bristol, is a mother of three, and eldest son Track has two children.
