Sienna Stevens, Ericca Laude prank Dingdong Dantes on 'The Master Cutter' set

Sienna Stevens and Ericca Laude had a hilarious time on the set of "The Master Cutter" after pulling a prank on Dingdong Dantes.

On "Fast Talk with Boy Abunda" on Tuesday, Ericca said they brought a plastic rat to scare their lead star.

"We asked him what's like your biggest fear or greatest fear, then he told me, 'I hate rats,'" Ericca said.

After getting that piece of intel, Ericca procured a plastic rat for the prank.

On set, Ericca and Sienna told Dingdong they saw a rat near the trash can, which was actually true.

"Then I threw [the plastic rat] behind him," Ericca said.

The two girls used their acting skills to make Dingdong look down and his surprised reaction was priceless. Mission accomplished!

Meanwhile, Sienna shared more about her bond with Dingdong's children. She recalled playing with Zia at an activity center.

"They're really fun to be with," Sienna said. "And Zia and Sixto are really kind."

She and Zia did some bracelet-making, made burgers, and tried cleaning a car.

"Then we ate at a Japanese restaurant. Super fun," Sienna said.

"The Master Cutter" airs weeknights on GMA Prime at 8 p.m. after "24 Oras." It is also streaming on Netflix.
