Dancing queen Francisca Paquita Morales showed off that she still has the moves.
The birthday bash was held at her senior apartment building in Humboldt Park.
The centenarian, who was born in Puerto Rico, moved to Humboldt Park 50 years ago. She's now believed to be Chicago's oldest resident.
She is the first to always get up and dance. Paquita says she attributes her longevity to faith, diet and movement.
Paquita has 13 grandchildren and 40 great-grandchildren.
