She’s rubbed elbows with world leaders, been hailed one of the world’s next great fashion icons over the past year, and made history as the first First Lady of color since moving into The White House in January, but at the U.S. Mission to the United Nations on Tuesday, Michelle Obama called her public service announcement for children’s television classic Sesame Street “probably the best thing” she’s done as First Lady.

First Puppy Bo just can’t compare to Elmo.

“I’m thrilled to be here, but I was just at ‘Sesame Street’ – I’m sorry,” the First Lady said as she thanked the diplomats and staff members promoting her husband’s new foreign policy of global engagement. “And I never thought I’d be on ‘Sesame Street’ with Elmo and Big Bird and I was thrilled. I’m still thrilled. I’m on a high.”

Mrs. O visited Sesame Street this week to tape a Public Service Announcement as part of Sesame Workshop’s Healthy Habits For Life Initiative. Mrs. Obama and longtime Sesame Street resident Elmo chatted about the importance of eating right, exercising regularly, and being a healthy and positive role model for kids.

“I think it’s probably the best thing I’ve done so far in the White House. But we were there talking about nutrition and healthy eating, and it’s just been a thrill.”

Always doing what she can for charity, Jennifer Garner attended a book reading session at the Rosemount Center in Washington DC on Tuesday (May 5).

According to PR insider reports, the pair were there to “launch the 2009 State of the World’s Mothers report, which presents alarming findings on the lack of adequate early childhood education across the country and around the world.”

Also among their duties, Jen and Pat are going to “explain the meaning and implications of the report’s findings in the United States as well as advocate for an increased federal commitment to American children.”

Even at his young age, the little guy revealed that he’s definitely his father’s son, sporting denim overalls, cowboy boot Uggs and a beanie.

Britney Spears has apparently found a new method of therapy: gardening. Because if there’s one person I want wielding hedge clippers, it’s Britney. The Sun reports:

A source said: "Britney has tried every kind of therapy going. She’s studied yoga, seen numerous counsellors and even experimented with mysticism, but they’ve never been more than passing fads.
"This time seems different though. She’s committed to learning as much as she can about horticulture and how it impacts your well-being.
"Whenever she returns to her California home she’s straight out in the garden working. She’s very proud and knowledgeable about what she’s planted and what is growing around her house."

I can just see Britney now, walking out to her garden with a plastic pail, shovel and dreams of growing a chicken wing tree. She planted one just yesterday down yonder. Though daddy says "a KFC bucket won’t grow nothin’," she knows the land. She knows the land.
