Alexa Ray Joel follows mom Christie Brinkley as new spokesperson for Prell shampoo

Alexa Ray Joel, the 24-year-old daughter of Billy Joel and supermodel Christie Brinkey, not only shares her mother's good genes--she's now following in her footsteps as the new Prell shampoo girl. In the commercial, Joel lathers up and tosses her lustrous hair exactly as Brinkley did over 25 years ago.

"Wanna hear a great tip I learned from mom?" asks Joel, referencing a photo of Brinkley that sits atop a piano. She goes on to talk about how the shampoo has been a favorite for generations. (Prell was introduced in 1947 by Proctor and Gamble, and quickly became famous for it's unique texture, clear green color, and rich foaming properties.)

In the latest commercial, Joel does have one unique advantage over her famous mom. She is a singer-songwriter, just like her father, and this Prell ad concludes with Alexa singing a few notes from her song, "Hideaway." Watch and compare the ads below:
