DEAL OR NO DEAL MODEL #25 ARRESTED for Dropping The C-Bomb

The chick who modeled briefcase #25 on "Deal or No Deal" was arrested Friday -- after she allegedly texted a very nasty word to her ex-fiance's new girlfriend ... a word that rhymes with BUNT.

Hayley Marie Norman
-- who's also appeared in the movies "Hancock" and "Fired Up" -- turned herself in to police in Los Angeles Friday afternoon ... after her ex's new GF told cops she had received an obscene text message from Norman last week .. which read, "You're a f**king c**t."

The new GF also complained that someone had vandalized the outside of her apartment by writing various messages ... including "This girl sucks d**ks for free" and "This girl is a f**king c**t."
