That's it from me today. I'll see you again on Wednesday for the first of the semi-finals, as Birmingham host Everton.
Until then, take care.
And please do head here for the rest of the day's football across the BBC.
Let's just recap on a dramatic afternoon:
Firstly, in our lunchtime kick-off at Goodison Park, Everton came from behind to beat league champions Chelsea 2-1 and shock the favourites.
Then holders Man City edged past second-tier Leicester, 2-1, in another cracking tie.
And then, after a 2-2 draw, Birmingham beat Brighton 4-2 on penalties.
It's been a classic day in the Women's FA Cup. You can find all our match reports here.
And the winners of those ties will meet at Wembley on 1 November. What a prospect.
Here's the confirmed semi-final line-up and schedule - both games will be live on BBC television (both kick-off times BST):
