Jessica Biel was a shy teen

London: Hollywood star Jessica Biel says she wasn`t popular with guys when she was young because they mistook her shyness for being aloof.

The 29-year-old actress, who is in a relationship with Justin Timberlake, says her insecurities made her seem reserved, reported Contactmusic. "I never (got chased by guys) as much as people might think. I`m quite shy, so sometimes guys would find me aloof because they`d think I was acting cool when it was just my nerves. It always takes me a while to feel comfortable in social situations or when I`m with new people," she said. As well as her shyness, Biel also admitted guys didn`t think she was pretty when she was younger. "I wasn`t considered attractive at all as a teenager. I was kind of an ugly duckling. But when I did Pilates competitions, I started to work on my appearance and body and was determined to make some of the nasty girls who tortured me feel jealous," she added. PTI
