'Hollywood Hillbillies' star, David Weintraub, just lassoed quite the Southern belle ... according to fellow star, Mema.

Weintraub popped the question over the weekend to Mallory Knighton ... and gave her a 3 carat diamond engagement ring worth $35k.

David was out with Ray J Friday, who said he's next to fall.

Mema tells TMZ, "Southern women are hard workers, great cooks, wonderful ladies in the living room, and whores in bed." 

So now we knew which one he'd f and which he'd marry.
