[Batman] Do Talia al Ghul and Catwoman know about eachother's respective romances with Batman?

What do they think of eachother, if they have had any contact at all?

At least pre-New 52 they did, and they don't like each other too much. 

Mostly because of their conflict over Bruce's affections, but also because of their personalities. Talia sees Catwoman as being not much better than any other criminal, and Selina thinks Talia is a clingy psycho with a superiority complex.

In Gotham Sirens, Talia even tried to get Zatanna to mind wipe Selina of her memories about Bruce under the guise of trying to protect his secret identity from Harley and Ivy, but it became apparent that it was also about eliminating the competition.
