TIMBERLAKE'S 'N SYNC PALS FEAR DIAZ'S WRATH

JUSTIN TIMBERLAKE's 'N SYNC bandmates refuse to discuss their pal's romance with CAMERON DIAZ – because they fear the actress will take violent revenge.

Timberlake and Diaz have been enjoying a romance for two years, but are fiercely against talking about their relationship in public.

And Timberlake's bandmate LANCE BASS has also been enveloped by the blanket of silence.

He tells US WEEKLY, "Cameron will kick our a*s if we talk about her!"
