Zac Efron's younger brother Dylan celebrated his birthday on February 6 and the star took to Instagram to share an adorable message in his honour.
"This is my brother Dylan- it's his birthday today - I love the crap out of him," Efron captioned the snap of the two boys onboard a plane cheekily smiling.
In the past Efron has shared a personal poem his brother once wrote about him in sixth grade.
Such a sweet bond. Happy Birthday Dylan!
