It looks like Carla Bruni, is taking a page out of Michelle Obama's style book and giving democratic fashion a chance -- um, as well as children's fashion.

As first reported by The Huffington Post, the typically Dior-clad French First Lady/model/singer performed "And I Love Her" alongside Harry Connick Jr. on "Le Grand Journal" wearing a T-shirt, jeans and shrunken band jacket from the Stella McCartney for GapKids line.

So, Bruni sang a Beatles song, wearing a Beatles-inspired jacket, designed by a Beatle's daughter -- we love it!

When StyleList chatted with McCartney at the launch of her Gap collection last month, the designer actually confided that she's been eyeing the fashionable "Miller" jacket -- named after her son and the most expensive piece in the collection, at $128 -- for herself.

"The military jacket is sort of the star of the show," she said. "If you take it up to the larger sizes, I think we can squeeze into it. I know I'm going to."

Perhaps the reason the Sgt. Pepper-themed jacket (which was also favored by Michael Jackson) is unavailable on is because adults (like these editors at Grazia UK) have co-opted the best pieces of the GapKids collection for themselves, à la Bruni.

Here's a look at the Stella McCartney for GapKids collection and the jacket Bruni wore, below.

In any case, we want to know what you think of Bruni's fashion choice: yay or nay?
