How do I tell my brother I hate his girlfriend?

My little brother is 18 and he's just gotten his first girlfriend who he met at college. Her name his chloe and she's also 18.

She loves social media and is very big into her insta and tiktok and wants to be a influencer as soon as I met her I just knew she wasn't a nice girl instantly but I thought to myself my brother is a grown man now and can make his own opinions and choices with people now and that I shouldn't judge her straight away.

They've been dating for 6 months and she expects so much from him. He got a job whilst at college and I was really proud of him but then I find out it's because he's trying to keep her happy with gifts and fancy dates which is nice too but she's so ungrateful and entitled it's disgusting.

He made her a boo basket because shed been asking for one, I'd never heard of this before and thought it was abit of a dumb idea but I took him shopping with me to primark and helped him out. I thought the stuff we got her was really cute but when she came over all I could hear was shouting upstairs saying it was a load of shit and but she was expecting something abit more expensive.

I wanted to go up there and tell her off but I held back because It isn't my business.

Then I find her tiktok and insta and there's loads of inappropriate pics and videos of her in her tiny little bikinis and they had loads of creepy comments on there and she was commenting back and loving the attention. It broke my heart, my brother loves her so much and this is how she treats him. Why would she need to most pics like that online if she was content with my brother.

After the boo basket Incident she stromed out the house and my brother looked really down. I gave him a big hug and he said "I'm never gonna be good enough, I'm so stupid "

I'm married to a fucking millionaire and I get flowers every so often if I'm lucky this girl is so ungrateful. Money can't buy love, easy to say for me yes but I'm not spoilt like that. Nothing wrong with a home cooked meal.
