<p><br /> Justin Timberlake has spoken about his two careers as actor and musician.<br /> </p><p><br /> "I feel very lucky to have the opportunity to do film, especially because I've been so lucky to have the opportunity to do music at a large level. So I just feel humbled by the whole thing to be honest with you."<br /> </p><p><br /> In spite of his acting success, Timberlake still plans to return to music. Although it has been over four years since his FutureSex/LoveSounds album, the 29-year-old says he will release some more material eventually:<br /> </p><p><br /> "I hope so. I hope that the next time I do it, it doesn't disappoint. I know it's been a little while and will probably be a little while before I do it. I don't put any projections on it. I try not to because I think that would negate the joy of creating it."<br /> </p><p><br /> Timberlake's latest film The Social Network is in cinemas now.<br /> </p>
