Miss Teen USA Winner Karlie Hay Admits to Using Language 'I Am Not Proud Of'

Karlie Hay said she previously used language she's "not proud of."

— -- Hours after being crowned Miss Teen USA, Karlie Hay took to Twitter to take responsibility for offensive language found on her Twitter page.

Many on Twitter claimed that Hay used curse words, issued threats and even used the N-word on her personal Twitter account, which is now protected.

The 18-year-old returned to the social network early Sunday morning to acknowledge her past tweets.

In a series of tweets she wrote, "Several years ago, I had many personal struggles and found myself in a place that is not representative of who I am as a person. I admit that I have used language publicly in the past which I am not proud of and that there is no excuse for."

Hay stopped short of expressing remorse for her past language, but she did say that she's changed.

The Miss Universe Organization, the parent company of Miss Teen USA, said in a statement to ABC News that though the language she used "unacceptable at any age and in no way reflects the values of The Miss Universe Organization," she will keep her crown.

"As Karlie stated, she was in a different place in her life and made a serious mistake she regrets and for which she sincerely apologizes," the statement said. "Karlie learned many lessons through those personal struggles that reshaped her life and values. We as an organization are committed to supporting her continued growth."

Hay was crowned the new Miss Teen USA Saturday night at The Venetian Resort and Casino in Las Vegas.
