'Bridesmaids' Scores At SXSW, While Katy Perry Tops The Charts In Today's Tweet Dreams

For a weekend that was filled with sad news, many took to Twitter, not only to spread the word about how people can do their part for those suffering in Japan, but for some brief escapism in the form of entertainment. Followers of singer Katy Perry learned the latest about her single "E.T." when she posted, "WE'RE #1 ON ITUNES! GREAT news to wake up to! Thank u for ur AMAZING support," while "Harry Potter" actress Emma Watson announced, "It starts with an L and ends with an E. I’m sure you have guessed the new face of Lancôme is me! :-)."

On the other end of the Hollywood spectrum came some particularly great news out of the 2011 SXSW Festival in Austin, Texas. The three-day movie, music and art fest has become a go-to spot for film premieres, which this year includes the comedy Hollywood Crush simply can't wait to see: "Bridesmaids." The flick—and particularly its star/co-writer Kristen Wiig (pictured here in a scene from the movie)—received raves from those who attended the screening. "Paul" star Simon Pegg praised, "It is without doubt the funniest film I have seen in a long, long time. LOVED it" as "The Back-Up Plan" sidekick Michaela Watson assured, "Saw screening #bridesmaids last nite.Hats off to Kristin Wiig 'n everyone else involved for revolutionizing womens' roles in comedy 4 ever!"
