Hailey Baldwin responds to Bieber haters on Twitter

Model Hailey Baldwin took to Twitter to say she's just friends with Justin Bieber, shooting down the haters who blasted her for getting too cozy with the singer.

After pictures of Baldwin, 18 and Bieber, 21, jet skiing in Miami showed the two appearing very close, she's gotten some pretty nasty comments on Twitter. But Baldwin held her ground, insisting she and Bieber are just friends. One lambasted her, saying he's always with "other girls but if you want to have no self respect do you boo @haileybaldwin."

Baldwin shot back, "I have nothing but respect for myself what I chose to do in my personal life is my business!."

Baldwin, actor Stephen Baldwin's daughter, has been fighting off hate from Beliebers for months. In December, she said she and Bieber were not dating, but that hasn't quelled the chatter. She said they've known each other for many years.
