Dr. Dre is a loving, monogamous husband who NEVER cheated on his wife with a big booty video vixen … this according to Dre’s VERY threatening lawyers.
The Doc’s legal team fired off a cease and desist letter -- obtained by TMZ -- to TheDirty.com ... demanding it remove blog posts claiming Dre is plotting to leave his wife for model Kili Anderson.
The website even posted pics of a house they supposedly screwed in together, and a huge ring Dre allegedly gave her.
The Good Doctor says the stories are B.S. and he's demanding The Dirty immediately 86 the posts and apologize ... or else.
We hear The Dirty is refusing to back down.
