Answer: Billy Idol
On the way to Las Vegas, Robbie Hart encounters Billy Idol in the first-class cabin of the airplane. After unsuccessfully trying to get a drink from the flight attendant, Robbie sees Billy and asks him if he would like a drink. In a nod to Idol's real-life musical career, his character tells Robbie that he is a musician, providing a moment of comedy between the two. The inclusion of a real-life rock star adds an element of authenticity to The Wedding Singer, which is set in the 1980s, a decade known for its music and pop culture icons. Idol, a British musician, was a prominent figure in 1980s music, and his appearance in the film is a clever reference to pop culture of that era. His brief cameo also provides a comical moment for viewers.
