In February 2010, Joel was chosen the new spokeswoman for Ultimark Products’ Prell brand of shampoo, with Joel’s songs to serve as background for commercials. New York Post sources said that Joel was persuaded to accept the commercial endorsement contract because of the opportunity to promote her music. Additionally, Joel was said to have liked the idea of succeeding her mother Christie Brinkley, who was the face of Prell in 1986.
In September 2013, Joel became part of The Gap’s “Back to Blue” television ad campaign, performing her interpretation of Billy Joel’s 1977 song “Just the Way You Are.”
