Big time happy birthday to the unofficial mascot of Loyola basketball. 

It's been about 18 months since Sister Jean became a household name as the adorable and punky nonagenarian fan of Loyola basketball. Today she officially became a centenarian.

That's right Sister Jean is 100 years old today and honestly, she doesn't look a day over 80.

The secret to her success?

ChicagoTribune - "I eat well and sleep well. And hopefully I pray well."

Congrats to Sister Jean on making it to 100. Hopefully, you'll be around for another Rambler run through March Madness.
