Your twoppic of the moment is Queen Rowling.  "Harry Potter and the Deathly Hallows: Part II," the final installment in the mega-popular movie franchise, premiered in London Thursday night... The stars of the film walked the red carpet...and got drenched thanks to a downpour.  But even with the rain, Emma Watson says it was a bittersweet evening... The Twittersphere is saluting the author of the Harry Potter series, including @HarryPotterish...

and @GrangerDanger...

Your twoppic of the day is #nationalchocolateday.  Yes, it is, and today is the day to celebrate the cocoa bean and all its delicious treats.  From chocolate bars to chocolate cake, from chocolate syrup to chocolate kisses...which is kind of funny considering Wednesday was #nationalkissingday...get your chocolatey deliciousness ready and enjoy.  Thanks to Twitter, we know @lolaalapo...

@DanielJonesChef...

and @Tasty_Morsels...

...certainly have been.

Your top twoppic is Taylor Swift.  The country queen has cancelled concerts for the first time in her young career... That could be part of it.  The 21-year-old has bronchitis, which has forced the postponement of Friday's show in Charlotte and this weekend's shows in Atlanta.  The singer might have foreseen her own fate---in a blog post last week, she worried that something bad would balance what she calls "a really beautiful summer so far." @upsidemeagan...

and @MattGoldich...

...are tweeting about it.  Swift's Twitter has been silent since she announced the postponement of her Louisville show earlier in the week...
