AITA for giving my sister a fake stripper that I hired and paid for?

I (28M) had my birthday party last weekend. My sister (18F) and her friends were at the party as well. She brought her new bf and I was cool with it, but also made it clear that there was going to be a stripper at the party and if he couldn’t handle that he should go home. He said it wasn’t a problem. Anyway the stripper showed up and my sister and her bf went outside and smoked weed for the duration of the time the stripper was there. <br><br>This was a stripper that I paid for, and she was my birthday present to myself. Anyway, my sister spent the rest of the night telling anyone who would listen that she is soooo much prettier and hot than the stripper I hired. She also made some comments about how I can’t even get a hot stripper and how I got a fat ugly one. This was starting to get to me because I paid good money for this girl and she was actually very hot. She was 5’11”, 130 lbs, and had dd cups. I think my sister is delusional if she thinks she is prettier than this woman. Anyways, the party goes on for a few hours and eventually the stripper has to leave. <br><br>My sister is still going on about how she’s so much prettier than the stripper, so I went up to her and said “you know, I really think you’re right”. I then proceeded to pull out a picture of the actual stripper I hired, who was way hotter than the one that showed up. It turns out the real stripper I hired got COVID and had to self isolate, and she hired another girl to replace her. I had no idea this was happening. I showed my sister the picture of the real stripper I hired, who was way more prettier than her in my opinion. I told her that the real stripper I hired couldn’t make it because she got COVID and I hired another girl who was clearly not as hot as the real one I hired. <br><br>My sister was not happy about this and is currently calling me an asshole. She thinks it was mean to do that even though she was being very critical of the girl. She thinks it’s mean to tell her I think another girl is prettier than her, but it’s not bad when she does it to the other girl. I think she’s being a brat and I don’t think I was in the wrong for telling her the truth. I also don’t understand why she thinks she can talk shit about the girl I paid for when she didn’t pay for anything.
