Gossiping mom

So for the past year I lived in a different state until recently when I moved back to where majority of my family lived. Some things went down this past year that are very personal and of course I talked with my mom about these things because who else would I talk to right? I was recently informed that at some family gatherings from the past few months my mom has been sharing pieces of information to different family members about me that I would rather her not. For example, she would tell an aunt about situation A and then 10 minutes later tell a cousin about situation B. These are deeply emotional things for me that are private and I haven’t talked to anyone else about.

I was wondering if anyone else has encountered a similar issue. What is the reasoning for her feeling the need to share my business? And how do I address it with her without the conversation becoming hostile. Me and my mom have a hot and cold relationship and in the past she has not dealt with confrontational issues very well when it comes to the two of us.
