Zac Efron makes surprise appearance on 'DWTS' to support brother Dylan Efron

Zac Efron made a surprise appearance on "Dancing with the Stars" to support his younger brother Dylan Efron on Tuesday night.

The "High School Musical" star was in the audience alongside his family to cheer on his 33-year-old brother, who is competing on the show with pro partner Daniella Karagach.

Dylan Efron and Karagach performed a tango to Prince & The Revolution's "I Would Die 4 U" and a cha cha to "Kiss," also by Prince & The Revolution, for the show's "Prince Night."

The pair earned scores of 27 and 28, respectively, securing a spot in the finale that's set for next week.

In a post on his Instagram story ahead of their performances, Zac Efron encouraged fans and followers to vote for Dylan.

The season finale of "DWTS," where the dancing couples will face off for a chance to win the Mirrorball Trophy, airs Tuesday, Nov. 25, at 8 p.m. ET on ABC and Disney+.
