Jak Roberto poked fun at his younger sister Sanya Lopez after watching her daring scene in the GMA-7 afternoon series Haplos.
In the episode aired on October 13, Sanya's character Angela performed a sexy dance number in a bar.
Angela is now known as the sexy bar dancer Exotica, after being kidnapped by Mama Sol, played by Maureen Larazabal.
With this new development, the 20-year-old actress had to wear two-piece suits and skimpy skirts while wearing a skin-tone body suit underneath.
In Jak's Instagram video that he posted on Friday, he held an arnis stick and jokingly shouted, "Nasaan na yung pamalo ko, ha!"
He then pointed the camera to Sanya, who was laughing the whole time.
Jak playfully scolded his younger sister and said, "Pumayag ka sa sayaw-sayaw na yun, ha! Dapa!"
The 23-year-old actor pretended to hit Sanya with his arnis stick, but his younger sister was able to wrest it from him.
Sanya became proficient in arnis after playing the Danaya character in GMA-7's primetime series Encantadia.
Danaya's weapon of choice in the telefantasya was arnis.
When Sanya gamely posed as if to attack him, Jak said, "Hindi na, hindi na."
Jak wrote in his caption: "Sa wakas nakita ko na pamalo ko #HaplosSayaw #Haplos"
Jak and Sanya, who both started their careers under the late German Moreno, are now considered GMA-7's fast-rising actors.
Haplos, which also stars Rocco Nacino, Thea Tolentino, and Pancho Magno, is now on its third month on the air.
