'Detective Pikachu's' premiere on Thursday wasn't just about the movie as Ryan Reynolds and wife Blake Lively caught everyone's attention with Lively revealing her baby bump. The 'All I See You' star Lively and Reynolds are expecting a third child together, as revealed by E! News. Grasping the theme character 'Pikachu' from the film, the mother-to-be wore a minimalistic yellow side-slit dress and embraced her newly developed baby bump.

"You wake up in the middle of the night; you got a big stupid smile on your face. I was telling someone else that. Anything else that woke you up every 45 minutes, you'd kill it. But when it's a baby, it's the best thing that ever happened to you," Reynolds told E! News earlier. Ryan told the crowd, "I want to thank my wife, Blake, who is sitting right there who is everything to me. You are the best thing that has ever happened to me."

He added, "You make everything better--absolutely everything in my life better. You've given us two of the most incredible children that I could ever hope to have. You've made me the father of my dreams when I thought I only had fun uncle potential." Ryan and Lively are already parents to two kids, a boy and a daughter. Ryan is playing Pikachu in 'Detective Pikachu' which will be released on May 10.
