Rocco Ritchie, Madonna’s son, dressed up like her ex-husband Sean Penn’s Fast Times at Ridgemont High character in an Instagram picture.

Ritchie’s Jeff Spicoli costume included a Hawaiian shirt tied up around his waste to make it into a crop top. Though Ritchie’s hair isn’t quite as long as Penn’s was in the 1982 movie, he wore his blond locks similarly tussled for the homage to the actor.

“Jeff Spicoli is alive and well in the South of France! #boom #fuzzy,” Madonna captioned the picture of her 14-year-old son with director Guy Ritchie.

Madonna, who divorced from Penn in 1989 after 4 years of marriage, posted the snap as a tribute on Penn’s 54 birthday.

In the years since their split, Madonna and Penn have maintained a friendly relationship. Earlier this year, Penn brought his current girlfriend and rumored fiancé Charlize Theron to the pop icon’s Oscar party in Los Angeles. Back in November 2013, Madonna took Ritchie with her to support Penn at a charity event he was hosting in Haiti.

Penn’s birthday, incidentally, came just a day after Madonna’s 56th. The Material Girl brought in her birthday in Cannes with children Ritchie, Lourdes, David, Mercy and her boyfriend Timor Steffens.
