1. Sheridan's not just our favourite character in Two Pints Of Lager And A Packet Of Crisps.
2. She's also the funniest star of Gavin & Stacey.
Remember Smithy's little sister, Rudi?
3. An incredibly talented stage actress.
4. And the best thing to happen to London's West End in the last five years.
5. Her range of facial expressions is exquisite.
6. She's adorable when she wins stuff.
That's her picking up a BAFTA for her role in Mrs Biggs.
