Madonna's eldest has caught the showbiz bug! The pop legend's 17-year-old daughter Lourdes played the role of Betty Rizzo in the production of "Grease" at LaGuardia High School Friday night -- with Madonna in attendance! Though the "Vogue" singer kept a low profile during the show in NYC, a source tells Us Weekly the entire auditorium was packed.
"[She was] really good," an eyewitness tells Us of Lourdes' acting chops. "The show was completely sold out, and people were scalping tickets beforehand."
"She is a great singer, dancer and actress and seemed completely comfortable on the stage," the insider adds. "She also seemed like she was having a lot of fun with the part."
During the show, Lourdes wore her Kabbalah bracelet for most of the scenes. However, when it didn't match with some of her wardrobe changes -- such as during the "Beauty School Dropout" number -- she decided to take it off.
Lourdes -- who was recently spotted visiting the University of Michigan with her famous mother -- will perform again during Sunday's show. Another actress plays Rizzo on Thursdays and Saturdays, the source explains.
But this isn't the first production Lourdes has taken part in. In her biography in the show's program, it states that she first debuted on the LaGuardia stage last year. Not to mention, the young actress thanks her parents in the short passage; her dad is fitness trainer Carlos Leon, with whom Madonna, 55, had a relationship in the '90s.
"Lola Leon (Betty Rizzo) is a senior Drama major at LaGuardia and this is her second annual musical. Last year she performed the role of Elaine in 'Sweet Charity' at LaGuardia and is very grateful to be able to participate in such an elaborate production for the second year in a row," the bio read. "Previous work in musical theatre before that include ensemble roles in 'Hair' and 'Cabaret' at ArtsEd in London."
It continued: "She would like to thank her parents with all of her heart for giving her guidance and love and supporting her passions wholeheartedly."
Leon, and Lourdes' siblings Rocco, David and Mercy were also in the audience for her big day.
