TWITTER NEWBIES. For the past three years, Twitter has become a rich source of information about virtually anything under the sun.

That includes, of course, news about our favorite celebrities who have flocked to the social networking site as well.

On several occasions, celebrities' tweets have sparked controversies, such as the recent post from actress Valerie Concepcion, which caused trouble for President Noynoy Aquino. (CLICK HERE to read related article) 

But despite the risks of getting embroiled in a scandal, the newbies readily joined the bandwagon.

Included among the celebs who appeared in Twitter this year: Regine Velasquez, Manny Pacquiao, Derek Ramsay, Jennylyn Mercado, Jake Cuenca, Angeline Quinto, Erik Santos, Ryan Bang, Chris Martinez, Aly Borromeo, Anton del Rosario, and Arnel Pineda.

iPAD2 ADDICTS. Apple founder Steve Jobs had the world weeping when he passed away on October 5, making it the biggest headline this year among the personalities who have left us.

But his legacy lives on in the hearts of millions of Apple gadget users worldwide—including some of our very own local stars.

While many of them already have their iPads from last year, they certainly did not miss upgrading to the new sleek lightweight model.

With a new video call feature called Facetime, the iPad2 has made it easier for celebrities to stay in touch with friends, even when they're filming in a remote location or doing shows out of town.

Also, there are more new applications available for almost every need—be it games or utilities—which celebs enjoyed using during their down time.

RUN, BABY, RUN! While the fitness craze became huge in 2010, it grew even bigger in 2011.

And with more and more celebrities becoming conscious about their health (and their figure, of course) many have turned to running for their basic cardio workout.

It is the simplest exercise one can do. Just pop on your running shoes, stretch and warm up a little, and then you're good to go.
