Since Bryan Randall got together with Sandra Bullock, he’s been spending a lot of time with the Bird Box actress’ kids — Louis, 9, and Laila, 7.

Most recently, he accompanied Sandra, 54, and the kids to a birthday party in Los Angeles on on Friday, June 7. Laila arrived wearing a cute green T-shirt that read “sunshine” on the front and Louis looked just as adorable in a gray T-shirt with black shorts and shoes. The best part about the outing was that Bryan held Laila’s hand every second of the way.

Even though Bryan is already a father himself to his daughter, Skylar Randall, he cares for Sandra’s children just as much as he does for his own. “The kids are growing up so fast,” an insider exclusively told Closer Weekly. “Bryan couldn’t be more involved in their upbringing.”
