Michaela Tabb has created snooker history by becoming the first woman to referee at the world championships.
Michaela Tabb took charge of Drew Henry's match
The Dunfermline official took charge as 11th seed Mark King unexepectedly lost to Scotland's Drew Henry 10-5 at the Crucible in Sheffield.
Tabb said: "I was nervous before I walked out. When the MC was introducing me, his words went right over my head.
"Towards the end of the first frame, I settled down and it just felt like any other match.
"It was a brilliant experience."
The 35-year-old mother-of-one moved from pool to snooker two years ago and is married to Scottish international Ross McInnes.
"Ross was playing in a pool tournament at the weekend and got as far as Carlisle to watch the first session but turned round because he needed to get back to play," Tabb added.
