Kellie Pickler has been keeping a relatively low profile since shaving her head for breast cancer awareness back in September -- but what a difference four months makes!
The former "American Idol" contestant showed off a pic of her longer 'do (and newborn niece) late last night.
"Finally!!! It's official...I'm auntie Kellie!!!!!! :)," the country singer tweeted along with the pic, which shows her holding an adorable baby and sporting short, cropped blonde hair. Don't they both look cute?
