Justin Timberlake is reportedly set to go gay for his next role - with a guest spot on hit sitcom "Will & Grace".

Sources say the 'N Sync singer, who has displayed his comedy skills a number of times on long-running show "Saturday Night Live", is planning to play the "bad boy" boyfriend of Sean Hayes' character Jack, reports the Internet Media Database.

According to reports, Timberlake has signed up for a three-episode run on the show when it returns for its eighth and final season in the autumn. Bosses of the show confirmed only that they have "some great guest stars" lined up for appearances.
