Selena Gomez\'s good mood was reflected in her clothing as she stepped out in a smiley face dress. Attending Hollywood producer Joel Silver\'s Memorial Day barbecue in Malibu, Selena was going for a friendly, relaxed look in a gray cotton maxi dress with what appeared to be two cut-outs at the chest. Despite her boyfriend Justin Bieber being absent from the party as he flew to Norway to begin his promotional tour in Europe, it didn\'t seem to affect Selena\'s upbeat mood. We liked the dress so much, it gave the young star a fashionable look and it is perfect for her age. Also at the barbecue: Ashley Greene, Josh Hartnett, Gwen Stefani, Gavin Rossdale, Robert Downey Jnr, Tobey Maguire, Barbra Streisand and James Brolin.
