Do a search on "Lacey vr Katie" on the clips4sale Bitchfight UK site.
Two fights - with different fighters - appear with the same title.
[The Bitchfight UK site could use a little editing.]
One of the fights has a preview with the fight you're looking for.
In the preview, the fighters are identified as Layce and Layla.
I haven't purchased this particular fight, but it looks like a good one.
