MIL is really annoying

My husband has always been really close to his mom. He's a huge momma's boy. I'm not trying to be mean but I just find his mom really annoying. She talks so much is so loud. Whenever I'm around her I tell her she doesn't have to yell. We are right here. She also always feels the need to hug my husband when we are around her. Full body hug. Not side hug. She is also sending stuff to my husband through Amazon. I feel every other week there is a package for him. His other siblings are pretty spoiled to but they are all still minors. I don't understand why she feels like she needs to spoil a grown man. I've tried talking to her because my husband would like us to be close but she always wants to talk about weird stuff that I know nothing about. She asked me did I know about the posh momma drama on tiktok and I said no. She was trying to explain this tiktok drama to me and I tuned her out. She will always call my husband to discuss weird stuff like that. He was on the phone with her for an HOUR because she was talking about this drama going around. Something about Willy Wonka. I don't get it. A weird story she loved to tell is how when my husband was young he was watching the Casey Anthony case and called her at the gynecologist to tell her the verdict and she remembered scream no in anger while her doctor had the little tool inside her. Out of all the memories you have with your son you remember the one where he calls you at the gyno? Weird. All in all she's just bizarre and annoying. I kind of just wish my husband's mom would disappear as crappy as that sounds.
