Get a sneak peek at the new Prell commercial, starring the 24-year-old daughter of Billy Joel and featuring a tease of the song "Hideaway," Alexa's own composition.
"Wanna hear a great tip I learned from mom?" Alexa asks at the beginning of the spot, walking next to a white grand piano with her mother's picture prominently displayed.
This is the first national campaign for Alexa, who was in the news last December after being hospitalized for a reported homeopathic overdose.
A statement issued by Ultimark Products, maker of Prell, said the brand had already seen growth since announcing its association with Alexa in February.
