I didn't know until the episode where it's Fiona's birthday that she was 21. I checked on IMBD and Anne-Marie Duff is 36. No doubt she is a great actress for the role of Fiona. But I thought her character was at least in her late 20s possibly early 30s. Does anybody else think that Fiona (Anne-Marie) does not look 21 at all?

I allways thought she looked the age of Fiona especially before i knew Anne Marie was 36.

I always thought she was about 27/28 in shameless , i dont remember her 21st in shameless ???

Monica mentions it at end of series 1 when she comes back she says she had it on list to send Fiona 21st birthday card

She doesnt does she??

when I first saw her actual age, I was like OMG
