It has been nearly five decades since the Pink Ladies, Rizzo, Frenchy, Jan, and Marty, first graced the screen in the musical film "Grease." The characters, known for their "cool" demeanor, played a pivotal role in shaping Sandy Olsson's transformation and her pursuit of Danny Zuko.

Didi Conn, who portrayed Frenchy, recently sparked nostalgia with a new beauty campaign for Laura Geller Beauty. At 74, Conn's campaign riffs on her "Grease" character's storyline as a beauty school dropout. In the advertisement, she muses about avoiding a life of constant salon appointments. Fans have reacted positively to Conn's youthful appearance and enduring personality.

Conn, born Edith Bernstein in Brooklyn, New York, began acting in her early teens. Her role as Frenchy in "Grease" was a significant early part, leading to roles in sitcoms like "Benson" and "Shining Time Station," as well as a reprise of her role in "Grease 2." She also voiced the character Raggedy Ann in "Raggedy Ann & Andy: A Musical Adventure." Conn made a cameo in the 2016 TV special "Grease: Live," making her the only original cast member to appear in all three "Grease" adaptations. In addition to acting, Conn is a figure skater and, at 67, was the oldest contestant on the eleventh season of "Dancing on Ice" in 2019. After divorcing her first husband, Frank Conn, in 1978, she married songwriter David Shire in 1984. They have a son, Daniel, born in 1992. Conn is also stepmother to Shire's son, Matthew. Her son Daniel was diagnosed with autism, and Conn became a spokesperson for Autism Speaks in 2008. She is slated to appear in the upcoming sports comedy-drama "Weekend Warriors."

Her subsequent work includes the CBS sitcom "The Stockard Channing Show," the drama "Without a Trace," and the miniseries "Echoes in the Darkness," which earned her an Emmy nomination. She returned to Broadway, appearing in plays such as "They're Playing Our Song" and "Six Degrees of Separation." Her performance in the 1993 film adaptation of "Six Degrees of Separation" garnered her Oscar and Golden Globe nominations. Other notable films include "Up Close & Personal," "Practical Magic," and "The West Wing." Channing has been married and divorced four times. She was in a relationship with cinematographer Danie Gillham from 1990 until his passing in 2014. Channing has no children and currently resides in London.
