Who am I?

I am a youtuber,

I love the color RED,

In most of my video you'll see me with a RED outfit,

and RED lipstick.

I am engaged,

I love singing,

I am also very daring,

In one of my video with Ryan higa,

I was dared to lick the HAIRIEST ARMPIT,

with peanut butter and i did.

And not only that I also 

dipped the tooth brush inside the toilet seat,

and brushed my teeth with it.

they were all dares;)

Who am I??
