If you don't like Oreos, then you have problems. In fact, if you don't like Oreos, I don't like you (... and if you don't like Thin Mint Girl Scout Cookies, you have even bigger problems). But you know who likes Oreos? Country-pop outfit Lady Antebellum, who celebrated the 100th birthday of the famed sandwich cookies with a performance and "Happy Birthday" sing-along in Los Angeles on Tuesday. Watch video proof below.

I've always had a soft spot for their track "Need You Now," but I like these Nashville radio rulers more now that I know I can sit down over a box of Double Stuf Oreos with them. Quality people. 

At their gig at L.A.'s Grove shopping center the band also played "American Honey" and "Need You Now," before leading a rousing rendition of "Happy Birthday" dedicated to a person in a Oreo outfit. A bunch of flash mobsters, presumably paid to cause a scene in the name of cookies (um, where do I apply?), helped out.

Mmmm... Oreos...
