People magazine is naming Jennifer Lopez the World’s Most Beautiful Woman. The singer, actress and “American Idol” judge tops the magazine’s annual list of “the World’s Most Beautiful” in a special double issue. Lopez is joined on this honor roll by such lovelies as Halle Berry, Jennifer Garner and Beyonce Knowles. Commenting on her lofty title, the 41-year-old Lopez said, “I feel happy and proud. Proud that I’m not 25!” … Drawing in everyone from Best Buy’s Geek Squad to the Afghan war commander fired by her husband, Michelle Obama ramped up her campaign to support military families on Tuesday and prodded everybody else in the country to get in on the act. The first lady, joined in the East Room by the president and Vice President Joe Biden and wife Jill, launched “Joining Forces,” an initiative to help military families who face a long list of unique challenges, such as moving around a lot and having a parent or spouse facing wartime perils far away. Mrs. Obama didn’t dangle federal grants or incentives, rather a call to be civic-minded. “This is a challenge to every segment of American society not to simply say thank you but to mobilize, take action and make a real commitment to supporting our military families,” Mrs. Obama said. Over the past year, Mrs. Obama’s primary focus has been an ambitious campaign against childhood obesity, in which she urged businesses, nonprofits, school and others to get involved in fighting the problem. As a down payment, the White House released a list of companies and groups that already have signed on to the effort, including Best Buy’s Geek Squad and WalMart.
