Mrs. Obama debuted her shoulder-length bob with eye-level bangs via Twitter on her birthday, Thursday, January 17, and she told Rocsi that Dr. Jill Biden may have had an influence on her.

"I've been coveting [Dr. Biden's] bangs for four years," joked Mrs. Obama, quipping that they're "the bang sisters." She also revealed that husband President Barack Obama gave her a "beautiful necklace" as a recent birthday gift.

On the topic of Lance Armstrong's interview with Oprah in which he admits to doping, Mrs. Obama said, "I didn't even get a chance to see it. It's a sad situation for everyone who's watching ... I think we have to remember all the people that have been helped and who will continue to need the help of [The Livestrong Foundation]. We should focus on making sure that cancer survivors and people dealing with the disease have the kind of support, medical and research, that they need to deal with the situation. We can't lose sight of that accomplishment."

Rocsi will present at tonight's Kids' Inaugural, which marks the latest efforts by the First Lady and Dr. Jill Biden's Joining Forces initiative to urge Americans to support our troops, and our Gold Star and Blue Star families.

The First Lady described the event in a video message, explaining that it's about "celebrating who we are as Americans and the people who make our country great -- our men and women in uniform, our military spouses, and our amazing military kids. So it's no surprise that when Jill and I decided to host this event, everyone wanted to join us -- from Katy Perry to Glee, from Nick Cannon to Usher. They know that military kids serve this country right alongside their moms and dads, and we’re really looking forward to celebrating our military families this weekend."
