Last weekend we pondered which "Gossip Girl" star would have a bigger opening weekend: Blake Lively in "The Town" or Penn Badgley in "Easy A"? While the teen comedy performed very well among moviegoers and critics, it was no match for Ben Affleck's crime drama (it raked in $23.8 million for the top spot at the box office.) Fellow "Gossip Girl" star Zuzanna Szadkowski gave props, as she posted, "I saw The Town this weekend. Some really cool scenes, and I thought Blake Lively was amazing." Meanwhile, "Glee" actor-dancer Harry Shum was clearly a fan of the flick, as he tweeted, "The Town was brilliant. Very impressed by every1s performance. Hats off to Ben Affleck."
While some celebs lined up at the theater, others took the stage for the final Jonas Brothers tour show in the U.S. Anna Maria Perez de Tagle wrote, "Wow. I can't believe we did it! U.S Jonas Brothers World Tour is over! Much love to my tour family..Until South America....
" There were some famous faces in the crowd too, including Wilmer Valderrama who told followers, "Just left the #CampRock2 concert, big shout out 2 the @JonasBrothers & @ddlovato for finishing your tour with a bang! Demi amazing job sist!" Rob Kardashian gave props to Demi Lovato as well, telling her via Twitter, "Just left @ddlovato concert. Took my little Sisters. Thanks Dem Dem!
Great show! Beautiful voice!"
