Zac Efron Shows Off His Big-Brother Skills in Rare Photo With His Baby Siblings

Zac Efron loves reporting for big-brother duty. On June 29, the actor threw it back to his "Greatest Showman" days when he took his little sister, Olivia, 3, and baby brother, Henry, to Circus Vargas in his family's hometown of San Luis Obispo, CA. He captioned his Instagram post, "Showtime," and added a clown emoji for good measure.

In the photo, Zac wore a bucket hat with his sunglasses perched on top (no bowl cut in sight). The proud big brother grinned as he held one sibling on each hip. Meanwhile, his little siblings wore matching smiles as their big brother carried them around the circus.

Zac also shared a video from inside the circus on his Instagram Stories. In the video, little Olivia sat on her brother's lap as they watched an aerial performance. Henry sat with his dad, David Efron, who joined his kids for their day out at the circus. The "High School Musical" actor's other brother, 31-year-old David Efron, couldn't join his family for their outing, but he still popped in to comment two red hearts on his big brother's post.

This isn't the first time Zac has shared photos of himself hanging out with his little siblings. Despite their age difference, the actor appears to have a special bond with his kid sister and baby brother. On Valentine's Day, he shared a snap of Olivia sitting next to him and cuddling a stuffed wolf while he read her a bedtime story. He captioned his post, "My valentine." And in December, he celebrated his sister's third birthday with a sweet post captioned, "Happy bday lil sis."

While Zac clearly enjoys hanging out with his younger siblings, they haven't inspired him to start thinking about becoming a dad just yet. During a 2022 appearance on "The Ellen DeGeneres Show," he explained he's not ready to be a dad. "I have a little bit more growing to do, probably," he said. "I don't know. Not yet."
