It appears Blake Lively and husband Ryan Reynolds will soon be outnumbered by their children.

The couple walked a yellow carpet Thursday for the premiere of Reynolds’ film, “Pokémon Detective Pikachu,” but it was Lively’s yellow dress – and what appeared to be a baby bump – that made big news.

Lively also was photographed placing a hand atop her belly, though the couple has not confirmed a pregnancy.

Ryan Reynolds' daughters make public debut

This would be Lively and Reynolds’ third child. They have two daughters: 4-year-old James and 2-year-old Inez.

Lively revealed her first pregnancy in 2014 in a similar fashion, with a picture of the actress cradling what appeared to be a baby bump but no explicit announcement.

Since getting married in 2012, the couple has been vocal about wanting a big family.

Reynolds told Details magazine in 2013 that they “both come from big families – my parents did four, Blake’s did five. A lot of people say it’s crazy, but we’ll only know when we’re there, you know? We’ll walk through that fire pretty happily, I think.”
