You already knew Kelly Clarkson won 'American Idol,' and now she's easily retaining her title of America's sweetheart, too. The 'People Like Us' singer had a meet and greet with fans at a stop on the Honda Civic Tour with Maroon 5, and she was basically a complete angel.

As if you didn't love her enough already.

The adorable Texan doled out compliments to her fans and gave a ton of hugs before heading to her vocal warm ups, where her powerhouse pipes basically gave her vocal coach a religious experience ... and check out her adorable spins!

Clarkson and her Maroon 5 tourmates Adam Levine and James Valentine also hit up the Children's Hospital of Philadelphia, where they hung out with fans who didn't hit the health jackpot. The meeting was set up through the Ryan Seacrest Foundation, which hooks sick kids up with their favorite artists.

So. Sweet.
