Zac Efron shares video of beach day with his siblings: See the sweet moment

Zac Efron is all about having fun in the sun -- especially if he's hanging out with his siblings.

The "Iron Claw" actor, 36, shared a video to Instagram on March 19 in which he and his younger brother Dylan, 32, are seen with their half-sister Olivia at the beach.

"First day of spring ☀️," he captioned the post.

The video begins with Efron holding Olivia, 4, and kissing her head as she announces that a wave is coming.
