Ex Beauty Queen -- Miss Demeanor?

Former Miss New Mexico USA Raelene Aguilar better put some extra Vaseline on her teeth and smile wide in court -- because she's just been charged with criminal DWI.

Aguilar was arrested earlier this month by El Paso,TX PD, after getting an F on her field sobriety test. She's now officially charged with one misdemeanor. Her first court date is April 23.

Aguilar's reign as Miss New Mexico USA ended in December, 2008.
