The nine-time CMA winner is featured in a 4-part Web series, “I’m with Wy,” which launches Aug. 20 at ABC.com.

The series featues Wynonna fan Lisa Graystone, who won a VIP fan experience, filming the singer as she accompanies her during the 2009 CMA Music Festival.

Highlights include Wy cutting up as she interacts with fans, does an interview on Music Row with Larry King, mingles with Darius Rucker and other artists at a radio junket and performs on the main stage at Nashville’s LP Field as part of The Judds for the first time in six years.

On Aug. 18, Wynonna makes a guest appearance on “Who Wants to Be a Millionaire” as the show celebrates its 10th anniversary.

The singer will compete to win $50,000 for charity. Wy’s winnings will be used to provide backpacks filled with food to children in impoverished homes in rural Kentucky.

And finally, Wynonna will make a pair of appearances on “Good Morning America.” On Aug. 18 she’ll drop in to preview her “Millionaire” appearance and on August 31, an interview she did with “All My Children” star Cameron Matheson at the CMA Music Festival will air on the show.
