Just because someone likes horses doesn't mean they look like one... I love Beyoncé and sometimes she prances on stage like a show horse, but do I see that as a bad thing? No... But I'd bet you if she loved horses people would say the same thing about her.
She's very pretty. Sometimes she gets caught at a bad angle, but if you saw her in real life she'd definitely turn your head. She's not a conventional beauty, she's more exotic.
She looked like a poodle/Clydesdale hybrid when she was on X-Factor but she, like Carrie Underwood, benefited immensely from a stylist and wardrobe change after winning. I think she looks great now.
