The name of American comedian "Bill Cosby" is trending in fifth place. Twitter users are spreading rumours about the actor's death on the social networking site.

Cosby took to his Twitter account (@BillCosby) to debunk the misinformation saying, "Again, I'm rebuttaling [sic] rumors about my demise. But, I'm confirming I have an app" and "Emotional friends have called about this misinformation. To the people behind the foolishness, I'm not sure you see how upsetting this is."

Twitter users just can't stop talking about science fiction blockbuster " Inception." The movie moves down one place on the charts to number six.

"The Jonas Brothers won the Latin American Mtv poll between Justin Bieber, that is why JONATICAS is trending" say people on Twitter explaining why "JONATICAS" is in seventh place in Twitter's trending topics.

Both the abbreviation for "clear" ("CLR") and "Shark Week" (week dedicated to shark-related programming on The Discovery Channel) have moved up one place over night and are now trending in eighth and ninth place.
