MARGOT ROBBIE BARE BABY BUMP ON VAYCAY WITH HUBBY!

Margot Robbie was out and about with her precious cargo … proudly parading her baby bump while living it up in Sardinia with her hubby, Tom Ackerley.

The pregnant actress was soaking up the chill vibes Monday — rocking a white blouse that was barely buttoned … giving the world a good look at her belly.

Margot had Tom right by her side, both of them keeping it cool as they beat the summer heat in style … and the pair sure look happy and relaxed with their baby on board 8 years after getting hitched.

No shock the “Barbie” star and her boo love a European vacay — they were living it up in Lake Como when their baby news broke in July.

As for the big reveal — boy or girl? That’s still a mystery. But, one thing’s crystal clear … Margot’s got that radiant pregnancy glow!
