UPDATE: Sunny tells TMZ she plans to fight the charges because she only blew a .08 ... the legal limit, by the way. As for her failed field sobriety test -- Sunny says she was wearing Christian Louboutins and "nobody could walk a straight line in those shoes."

Sunny Cross
, who was on the very first episode of the MTV show "Catfish," was arrested this morning for suspicion of driving while intoxicated ... TMZ has learned.

Cross was popped at 8:20 AM in Fayetteville, AR. According to the website for the Washington County Sheriff's Office, Cross was popped for driving too close to another vehicle, driving on the wrong side of the road, and lastly ... DWI.

Cross posted $1,055 bond and was released at 9:39 AM. Oddly enough ... at 8:39 AM she tweeted, "Last night was hilarious."

We called Cross for comment and got her voicemail. A few minutes after we called, she tweeted, "Well I guess it's safe to say last night was an epic fail."

Cross appeared on the very first episode of "Catfish" -- where she was "introduced" to her Internet boyfriend, who turned out to be a girl named Chelsea.
