Zac Efron is coming alive with big brother duties.
Case in point? The Greatest Showman star's latest family outing in his hometown of San Luis Obispo, Calif.
On June 29, Zac shared a photo of himself carrying his 3-year-old sister Olivia and baby brother Henry in his arms during a visit to the greatest show: Circus Vargas. The High School Musical alum, 35, captioned the smiley snapshot on Instagram, "Showtime."
And you can bet on it that the Efron clan had a blast. As seen in a video posted to Instagram Stories, Zac and his siblings were in awe as they watched an aerial act from the crowd.
"Wow," exclaimed Zac, who was pictured with Olivia in his lap. Meanwhile, his dad, David Efron, was seen sitting with Henry as the group cheered on the performers.
The Baywatch actor's brother Dylan Efron, 31, also approved of the cute circus day, bopping to the top of the comments section with two heart emojis.
But while Zac is happy babysitting his siblings, fatherhood is not what he's looking for at the moment. After playing a dad in 2022's Firestarter, he admitted, "I think that was a healthy dose to put me off of it for as long as necessary."
"I have a little bit more growing to do, probably," he said during a May 2022 appearance on The Ellen DeGeneres Show. "I don't know. Not yet."
