Paris HiltonParis Hilton is vacationing in Amsterdam this week, doing fun things like playing with native pigeons (who clearly have the munchies). Animals all over the world will rejoice to hear that Hilton, according to her caption, loves “ALL animals no matter what.” @barrefaeliBar RefaeliBar Refaeli is clearly having an awesome Friday, posting a gorgeous beach pic in the middle of the workday. While the magnanimous model captioned this gem “Have a magical weekend guys,” we’re pretty sure we’ll spend the majority of the weekend coming to terms with the fact that no Instagram filter can make us look like Bar Refaeli. @britneyspearsBritney SpearsOn Tuesday morning Britney Spears was flown in a helicopter to the Nevada desert to officially announce her two-year Las Vegas residency on Good Morning America. Not since the Wright brothers has one flight meant so much to so many. This Twitter pic, with the soon-to-be-iconic caption “We’ve got liftoff,” will surely go down in pop-culture history. @bravoandyAndy CohenJust in case you thought this gallery couldn’t out-camp a two-year Britney Spears Las Vegas contract, Bravo’s Andy Cohen posted this pic on Friday, offering a tantalizing glimpse of a “#QueerEyeReunion Coming Soon.” This is great news for straight guys, who have been living in dirty hovels and grooming themselves without hair products since the show was cancelled in 2007. @lenadunhamLena DunhamLena Dunham really shined on Instagram this week. In this shot, the writer, actor, and possible voice of her generation posed with a bra on her head. You know, just doing girl stuff. @AvrilLavigneAvril LavigneAccording to this Twitter pic, Avril Lavigne and her crew “RockNRolled” on Jimmy Kimmel Live. Judging by the photographic evidence, Lavigne’s definition of RockNRoll involves a lot of eyeliner, pained facial expressions, and a token old guy. @nickiminajNicki MinajIt looks like all of Nicki Minaj’s multiple personalities love her fans. And hats. The rapper and wig enthusiast took to Instagram this week, declaring “All around the world. The #Love always shines thru.” @iansomerhalderIan SomerhalderIf you were worried that Ian Somerhalder is nothing more than a perfect body and beautiful face, don’t be: apparently he also has a sense of humor. And he knows how to use Photoshop, as evidenced by this Instagram prank he played on his costars. We’re guessing The Vampire Diaries star’s work of art will be all over Tumblr in no time. @darrencrissDarren CrissSpeaking of Tumblr fodder, teen heartthrob Darren Criss gifted the world with this solo shot from Toronto’s We Day. The educational event features a variety of change-makers and inspirational speakers, as well as Demi Lovato and The Jonas Brothers. @taylormomsenTaylor MomsenA lot of former child stars attempt to play with their image and work beyond their comfort zones. But few of them can actually pull off nipple pasties. Taylor Momsen, of Gossip Girl fame, tweeted this pic to promote her new single, “#GoingToHell.” Move over, “Wrecking Ball.” @badgalririRihannaEven Rihanna takes time out of her busy schedule to pic stitch Instagrams and come up with witty captions (or order her assistant to do it). Stars: they’re kind of like us! @tyrabanksTyra BanksIn this classy black-and-white twit pic, Tyra Banks is attempting to recreate “the iconic Linda Evangelista signature look.” Banks often tweets about a series of shoots she’s doing in the style of other famous models. Much like the 20th cycle of America’s Next Top Model, it’s unclear if anyone actually asked Tyra Banks to do this.
