Blake Lively is celebrating National Siblings' Day with her lovely family.

On Sunday, the actress added a photo on Instagram that shows her with her brothers, Eric and Jason, and her sisters, Robyn and Lori. The gang is crowded together with big smiles as they look like best buddies.

Lively added some red hearts around the image and captioned that her parents are "breeders."

 Happy national sibling day. Yes, our parents are breeders.

Lively is married to Hollywood hunk Ryan Reynolds. They have one daughter together, James, 1.

The actress has been busy with marriage, being a mom and her career. Her next summer film will be The Shallows where she plays a surfer who gets stranded on a rock in the ocean after a shark attack. Even though her character isn't too far off from land, the shark is in the water, leaving her in a nasty battle.

Speaking to Entertainment Weekly about her role, Lively said it was her husband who inspired her to take it on after he was in a film with a similar concept. He played a man trapped six feet under in a coffin with only so many objects.

Now Lively is in a movie that takes place mainly on her in just one spot, a challenge that Reynolds was given credit for.

"My husband did a movie called Buried and that was one of the reasons why I wanted to take on this movie so much because I know how tough that was for him and how rewarding it was," the blonde beauty said. "It was terrifying and one of the most vulnerable things you can do, but you gotta do it, right?"

See the trailer for The Shallows below.
