It was the premiere of Pokeman Detective Pikachu but the big premiere of the night wasn't the film, it was Blake Lively's baby bump!

The soon-to-be mother-of-three showed off her growing belly in a Retrofete yellow sequined dress tied above the bump with a silk sash. Hubby Ryan Reynolds wore an eclectic denim vest under his biege suit but it was his wife who really stole the red carpet.

Congrats on baby #3 for this beautiful couple!
