Celebs taking a break from microblogging

SOME of the big stars on Twitter have recently retired from sharing the minutiae of their lives in bite-sized online updates.

And while celebs including Miley Cyrus and Courtney Love have given up on micro-blogging voluntarily, others have been muzzled by their employers.

Reports surfaced this week that Cameron Diaz and Mike Myers have signed contracts that demand they refrain from Tweeting about the upcoming Shrek movie, though their reps have since denied it. And the NBA and NFL have taken steps to limit the amount of updates their players dole out — particularly around game time.
