Canadian pop star Carly Rae Jepsen speaks out on her age, which she says she is totally happy with. Although 27 is young relatively speaking, for a pop star it seems ancient in contrast to Justin Bieber's mere 18 years. If it wasn't for Bieber's mentoring though, the "Call Me Maybe" singer might still be an unknown. The spoof video he and his friends made helped spur her song to its viral status. Plus, appearing with her for important events like her debut on Ellen DeGeneres helped boost her popularity quickly. Regardless of age, both pop stars have had a great year, winning big at the 2012 AMAs!
