Tori Spelling is proud of her pregnancy curves -- and showed them off over the weekend in a very skimpy black monokini.

The 39-year-old, who is currently pregnant with her 4th child, flaunted her body in a daring two-piece held together by mesh in the middle while at a Memorial Day BBQ on Monday in Malibu.





The actress-turned-reality star posed in the risque swimsuit with 7-month-old daughter Hattie and hubby Dean McDermott ... who was wearing Affliction board shorts.
