I think my brothers girlfriend is cheating on him?

so my brother has been dating a girl for exactly 1 year as of yesterday. very nice girl, friendly, i like her, and looks like they love each other and that's great.

one Friday night at 12 i asked my brother where she was and he she's with her sister... and i hung out with my brother till 2-3am and she still was not home.

the week after that the same thing happened. she went out at 10pm to her sisters and she had makeup on SHE NEVER WEARS MAKEUP.

now here is why i am suspicious of her... she used to be a stripped in las vegas. and who knows what else she would do. and on top of that, she is very insecure.

i am seriously suspicious of her and i want to follow her one time im not kidding.

my brother is 29 years old and she's 24 going on 25. i am worried for my brother

i'm not saying she's not allowed to go out and have fun with friends/her sister but just something about it doesn't sit right with me. i kind of have a 6th sense
