Kate Middleton is turning up the heat when it comes to her gala gowns.
On Thursday, the 32-year-old Duchess of Cambridge rocked this stunning semi-sheer Temperley London frock to Action on Addiction's Autumn Gala Event, and you would never have been able to tell that the royal beauty was already four months pregnant.
While Kate obviously kept her sheer style a little more conservative than most other celebs seem to, she did show more skin than we've seen from her in the past.
The Duchess accessorized her black ensemble with black pumps and a delicate black clutch. All of which went a long way in showing off her massive diamond, and apparently hiding any hint at a baby bump.
This was one of only a few appearances Kate Middleton has made since she and Prince William announced in September that they were expecting their second child. Check out the video below for more royal baby news.
