Ric Flair's Ex-Wife -- Arrest Warrant Issued for Harassing His Girlfriend

Ric Flair's ex-wife is being hunted down by police in North Carolina ... and TMZ has learned its all because she was allegedly threatening the Nature Boy's new girlfriend.

A rep for the Mecklenberg County Courthouse in North Carolina tells us an arrest warrant was issued for Jacqueline Beems at the end of June.

We're told the warrant stems from a series of harassing phone calls she allegedly made back in October to Flair's GF Wendy Barlow Kidder -- who recently appeared with the wrestler on "Celebrity Wife Swap."

However, cops wouldn't go into detail about the harassing nature of the phone calls OR why she took so long to file a complaint.

FYI -- Flair and his wife were still legally married at the time of the alleged threats.
