Is it a good sign if the girl I've been talking with knows some info about me I told to our mutual friend?

There is this girl I like and been talking and texting for a while and yesterday while texting I wanted to tell her something that happened to me and she told me "she heard about it" and only way for her to know is through our mutual friend, which is one of her best girl friends. And I'm sure she didn't tell her that just out of gossiping cause there is nothing to gossip about it.

So, do you think they actually talk about me? And could that be a sign she is interested in me? by the way I asked her out and she said yes, we still haven't gone on date cause we are both busy atm.
