AITA gf finds escort page open on my tabs.

So a little back story is one of my chick friends told me about her selling her kitty on a website. I kept inquiring questions about it and then she sends me the link and then I open the link and click through some girls and just look around. Btw I have no interest in at of the kitty’s for sale. I had a loving GF that fulfilled all my needs. I was just clicking around and left all the tabs open and then she is trying to open something on my phone while driving. She ask me what’s all this and I told her straight up what it was and then explained that I got the link from a friend and opened it. I told one of my guy homies and he says it really does look like I was looking for kitty but I’m 100% honesty it was just a huge mistake and misunderstanding. I know I shouldn’t be looking at stuff like that but I was and I got caught for it I was actually was going to tell her later on in the night but she was helping me while driving and talking about her day. AITA ??
