More proof that Jennifer Garner and I are soul sisters! My husband is always yelling at me that my underwear is hanging out. I try to tell him that I can't help it, when I'm wearing those pesky low-rise jeans and I'm playing with my kid on the floor. Obviously, Jen has the same problem. I'll admit this photo is slightly disturbing, a little too much plumber's crack for my taste, but I still love her -- she's just doing her thong, um, thing.
