Tammy Hembrow's sister Amy is expecting her first child with fiancé Rory Carmody.
And on Saturday, the sisters celebrated with an engagement lunch at The Bower Estate in the Gold Coast Hinterland.
In photos shared to Instagram, Tammy, 25, dressed to impress in a racy white frock that showed off her cleavage, tiny waist and defined legs.

Her long blonde locks were styled out and in a deep side part, and her makeup included bold brows, false lashes and a slick of pink colour on her plump pout.
In one photo, Tammy sat at a dining table and posed with a glass of wine in hand.
She looked down at the floor, drawing attention to her false lashes, and left her lips agape.
