Talk about a sweet celebration!
In honor of Oreo's 100th birthday, Lady Antebellum showed up at The Grove on Tuesday morning to belt out a few of their hit tunes in a surprise free concert for one of America's favorite cookies!
Before singing "Happy Birthday" to a giant Oreo (yum!) the Grammy winning band kicked off a Happy Birthday flash mob, which was just one of seven similar celebrations that took place across the country in honor of the delicious treat.
After 100 years Oreo, you haven't aged a bit!
