Tres chic! Yesterday the Cannes Film Festival kicked off for that 63rd year in France, and will, as it always does, feature a bevvy of stars (including Nicky Hilton, who told followers, "Next stop--->Cannes!") and buzzed-about movies. This year's festival started with the worldwide premiere of "Robin Hood," which had a large turn-out, both for that screening plus the after-party. One individual who seemed to be enjoying herself was Eva Longoria who posted an enviable pic, "Me and gael Garcia Bernal last night at Robin Hood party. Good movie! http://bit.ly/cqNn0D."

Meanwhile, making waves on our side from the pond, is 12-year-old Greyson Chance (pictured), who has turn out to be a viral sensation by looking like Justin Bieber and, much more impressively, singing like Lady Gaga. Not just did Ellen DeGeneres have him on her show right now, posting, "This is 12 yr old Greyson Opportunity. Write that name down, memorize it – I've a feeling you’re gonna be hearing it A LOT.http://bit.ly/dnpGjV," he even got a surprise from Gaga herself, as Ellen tweeted, "Thank you @LadyGaga for calling during the show right now – pretty certain you produced Greyson’s year & I often love talking to ya!" (Check out YouTube to see Greyson's original video).
