The "Gossip Girl" star and her "Deadpool" actor husband have officially added another family member, reports Us Weekly.
According to the outlet, Lively gave birth earlier this summer to their third kid but has kept it under wraps.
The source told them that the baby is “about 2 months old.”
It's not surprising that Lively and Reynold's would keep the baby news to themselves, considering she recently just revealed she was pregnant.
Sporting a large pregnancy bump on the red carpet in May, the actress surprised everyone with baby #3.
Lively wore a gorgeous yellow sequined gown that hugged her growing belly during the premiere of her husband's movie, "Pokémon: Detective Pikachu."
The couple is already parents to 4-year-old daughter James and 2-year-old Inez.
Reynolds has joked about parenthood in the past, stating he’d “rather drink a piping hot bowl of liquid rabies than get on a plane” with his little tykes.
Gushing over his family in 2016, the actor told Marie Claire, “All my eggs are in one basket, and that’s my family. That’s where my heart is. That’s where my everything is. That’s the thing that I feel most protective of and the thing that I feel is the most exposed when I feel exploited.”
Lively and Reynolds tied the knot in 2012.
Prior to their marriage, the actor was married to Scarlett Johansson from 2008 to 2011.
