Does Mischa Barton have pierced ears?

Answer 1

Yes, she has.

Mischa originally had her ears pierced when she was in her early teens, but stopped wearing earrings and let the holes close up before she started on The O.C. After that, she could only wear clip-on earrings. At the start of 2009, she agreed to have her ears re-pierced especially for her role as Sonja on The Beautiful Life, so that she could wear the same style of earrings as all of the others on the show.

Apparently, when she had them re-done, she went to a piercing parlour and had them done with a needle, rather than going to a high street place and having them done with a gun. And, rather than having studs or small hoops, she had some clear plastic "keepers" put in for the initial healing time, which are designed to be very hard to see - they're really meant for hiding piercings at work if people are banned from having piercings - and that's why it wasn't obvious that she'd had them re-done.

Answer 2

Yes, she does - she had them pierced at the start of 2009 for her role in The Beautiful Life.
