Watch: Lion Cubs Pass Swim Test At National Zoo The day was a roaring success for four adorable lion cubs who passed their swim tests at the National Zoo in Washington D.C. The cubs - three boys and one girl - were born 10 weeks ago at the zoo. The cute cats paddled and managed to keep their heads above water as they swam across a pool and made their way to dry land. The swim test was a crucial step for the cubs before they join the zoo's exhibit, which is expected to happen in mid-June, according to ABC News' Washington D.C. affiliate WJLA. The next step on the to-do list for the cubs: vaccinations.

Hollywood Turns Its Back on Famous Hotel Because of Brunei's Ownership The Beverly Hills Hotel is as famous for its pink walls as it is for all the celebrities who have checked in for a stay. Numerous movies have been filmed there, including "American Gigolo" and "The Way We Were." But recently, some of Tinseltown's biggest names have turned their backs on the hotel known as the "Pink Palace." The Beverly Hills Hotel and the Hotel Bel-Air are operated by Dorchester Collection Properties, a group owned by the Brunei Investment Agency - an arm of the Brunei government ruled by Sultan Hassanal Bolkiah.
