Ex-White Stripes drummer Meg White turns 50 today (Tuesday), and Jack White celebrated her with a new post on Instagram.
Jack shared a photo of Meg and wrote, "Happy 50th birthday to my big sister, the great Meg White. There's only one of you Meggo, they broke the mold. You're still inspiring people, including me. Love you so much."
Of course, Meg is not Jack's sister -- she's his ex-wife. They were married from 1996 to 2000, and the then-Jack Gillis legally changed his last name to White when they got married.
