Oh, Blake Lively and Leonardo DiCaprio. We hardly knew ye. The mutually blond lovebirds have called it quits after nearly sixth months together, with details scarce, but reps for both actors insisted to outlets including Us Weekly that the pair "remain friends." Just no longer the friends-with-benefits variety. Lively is back to work on the CW's "Gossip Girl" after a filming a feature in Los Angeles this summer.juicy couture DiCaprio remains busy, currently shooting Baz Luhrman's 3D "Great Gatsby" update in Australia and chilling at the top of the year's highest-paid actors list. After picking up tabloid steam starting in June, DiCaprio and Lively enjoyed quality yacht time at the Cannes Film Festival, followed by street shopping in Monte Carlo. DiCaprio bounced to Lively on the heels of another "off" with his on-and-off model love Bar Refaeli. Blake previously dated her "Gossip Girl" costar Penn Badgley. The total loss of Ozone in the Arctic was over double the typical amount in the Antarctic, but the area of loss was 40% smaller. Ozone depletion occurs in an atmospheric cyclone system known as an Arctic polar vortex. Whereas the Antarctic vortex is larger and longer-lived, the northern vortex is smaller and shorter, but it is also mobile and often moves over densely populated regions, potentially endangering humans to direct UV exposure.
