With big yellow glasses, blonde hair and a flowy tunic, Painting with a Twist co-founder  and CFO Renee Maloney went under the radar at her own company on tonight's episode of CBS' "Undercover Boss." 

The Mandeville-based paint-and-sip business Maloney formed with friend Cathy Deano after Hurricane Katrina has grown to 320 studios in 36 states.

In the episode, Maloney hit the road, popping in on three of the franchises — those in San Antonio and Rockwall, Texas, and in Royersford, Pa.; as well as visiting the business' third-party supplier, Louisiana Art Supply in Hammond. 

Painting with a Twist co-founder Renee Maloney has a confession: She failed art.

There, it's out there. However, it didn't stop her and friend Cathy Deano from launching their paint-and-sip business in 2007 in Mandeville. Franchising began two years later, and there are now 320 studios in 36 states.

She wanted to see if the franchises were running smoothly, or if there was room for improvement. She also wanted to give back — an integral component of PWT's simple yet successful business model.

So Maloney listened as she worked, posing as Savannah, a single mom trying to win a reality show to help support her family. She heard stories from those she worked side-by-side with that touched her heart.

In the end, Maloney revealed her true identity and surprised shift manager Calvin at the Hammond warehouse with $5,000 to help grow his vending machine business and $10,000 for his daughter's education. Artist Maci in San Antonio got $50,000 for her education, $5,000 to visit her mother, and $10,000 rent. In Royersford, franchisee owner Steve received $10,000 to compensate him for social media training he enrolled in on his own, and Mahoney's sending Steve and his family on a Disney cruise.

Maybe the biggest change is in store for artist Bree in Rockwall. Not only did the "boss" gift her with $20,000 for a rainy day, she gave her her own Painting with a Twist franchise.

"I'm crying so much, my eyelashes are going to fall off," an ecstatic Bree shouted.
