Jennie Garth, Peter Facinelli Divorce: Garth Opens Up About Being A Single Mom (VIDEO)

Jennie Garth is opening about what it might be like to raise her three daughters as a single mother.

In an exclusive preview of Garth's upcoming CMT reality show posted by ET Online Friday, the 39-year-old actress -- who announced her separation from husband of 11 years, Peter Facinelli, on Tuesday -- talks candidly about what's next for her family.

"Being out here on my own with the girls is not going to be easy, but I know it's the right thing for us right now," Garth said. "I feel it in my heart. I'm excited about what's next."

The show, "Jennie Garth: Little Bit Country," follows Garth and her daughters, Luca, 14, Lola, 9, and Fiona, 5, as they leave the Hollywood life behind for simpler days on a Santa Ynez Valley, Calif. farm. The split is expected to be covered in the series, though Facinelli will not make an appearance, according to People magazine.

Garth, whose first marriage to Daniel Clark ended after two years in 1996, wed Facinelli in January 2001. On Wednesday, Garth and Facinelli, 38, denied allegations that cheating had played a part in their split, calling the rumors "hurtful."

"Jennie Garth: Little Bit Country" premieres on CMT on April 20.
