Blake Lively and Ryan Reynolds welcome their fourth baby together

Congratulations are in order for Blake Lively and Ryan Reynolds ...

The Hollywood power couple have welcomed their fourth child together!

While the pair haven't officially confirmed the news, the 35-year-old actress took to Instagram to share a string of photos enjoying Super Bowl celebrations, without a visible baby bump.

"Puppy Bowl Sunday 2023. Been busy," she wrote alongside the snap of her with her Deadpool star husband and his mother Tammy Reynolds.

The couple, who try to keep their family life private, already have three children together - James, seven, Inez, six and Betty, three - and have gushed about parenthood in rare interviews.

"My husband and I chose a profession and a side effect of that is your personal life is public," Lively previously told Marie Claire UK.

"Our child hasn't had the opportunity to choose whether or not she wants her personal life to be public or not. So in order to give her as much normality as possible, we want her to have a childhood like we had."

"There have been times where I woke up, literally had no idea I had been walking for five minutes," Reynolds previously said.

"But you love it. 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."

Congratulations Blake and Ryan!
