It's a tie between Rihanna and Lady Gaga, but since I voted Lady Gaga as my most liked in the other poll, I went with Rihanna.
I actually actively dislike Lady Gaga; she comes across as incredibly fake and try hard, and the meat dress incident made me
despise her as a public figure.
I'm honestly pretty indifferent to Rihanna because she's not particularly offensive as a person, but I find her very try hard as well. She seems like she wants really badly to be shocking and trashy and hip, but she has to try way too hard to achieve it (and even then, I don't think she really achieves it
). Unlike Gaga, she's not creative or talented, and her music is generic and lackluster.
