Songfacts®:

• This electro-pop track is the debut international single of Eva Simons, a Dutch singer who boasts a bright red Mohawk. She first came to public attention in Holland, after winning the Dutch version of the reality TV show Popstars. Simons became a member of a girl group called Raffish, who had a #1 hit in their home country with "Plaything." She was signed by EMI after this song was leaked onto YouTube and swiftly clocked up several million hits. Its popularity was enhanced by many pop fans mistakenly guessing it was a demo by Lady Gaga or Rihanna.
• Simons wrote this with Tearce, her co-writer and producer. She told Digital Spy about the song: "We wrote it in 2008 when I was working on my album. It's about a guy I know who's an a--hole. Some people would call him a "player" or a "Casanova", but those words have kind of become compliments. There's no way anyone could say 'Silly Boy' is a compliment. No guy wants to be called a silly boy."
  Digital Spy asked Simons if the guy knows the song is about him. She replied: "I think he knows now because I've been calling him 'Silly Boy' for a while. He's down in my phone as 'Silly Boy' too."
