The actress debuted her growing baby bump last week at the Pókemon: Detective Pikachu premiere in New York City, letting the world know that she and hubby Ryan Reynolds have another baby on the way.
Lively looked absolutely stunning at the premiere in a bold yellow dress from Retrofête, which accentuated her bump with its belted silhouette and matched the Pikachu-themed yellow carpet perfectly.
She accessorized with colorful chandelier earrings, gemstone rings, a wrist full of bracelets, and multicolored ankle strap heels.
This will be Lively and Reynolds third child together. The couple, who wed in 2012, is already parents to 4-year-old daughter James and 2-year-old Inez.
Details on baby #3 are still under wraps, but we do know that Reynolds has said he wants to have more daughters. He told PEOPLE that being a dad to two daughters has been a "dream come true."
"Having a daughter was a dream come true for me. If I could have nine daughters, I would be thrilled. Really, like I genuinely would be," he said back in 2016.
