"Obvious Child" star Jenny Slate says she totally regrets getting a belly button ring when she was 20. Here's her explaining it to Cosmopolitan.com last week:  "I have a scar — it's such a bummer," "I had really long hair with crunchy gel and I was into midriffs" — and removed it two years later. "My mom had a total conniption [when I got it]; she was so upset. And I'm upset that I did that. It's so gross. Now I have a scar that's so heinous."
