Jason Francisco punches John Prats on set of 'Banana Split'

PINOY Big Brother ex-housemate Jason Francisco engaged in a brawl with John Prats on the set of comedy gag show "Banana Split" Thursday night.

The incident took place at the Music Museum in Greenhills, San Juan City, during a taping for the show's future episodes.

"I was watching the rehearsal ng Banana Split. There from behind, sinapak niya ako ng dalawang beses sa mukha," John said in a late night interview on "Bandila."

The show's director Jemster Reyes, who was with John when Jason attacked the actor, witnessed the whole incident.

"Akala ko tatapikin lang niya si John. Yung tapik niya, isang malakas na sampal sa kanan, tapos suntok sa kaliwa, tapos suntok ulit. Bale tatlo. Tapos inawat na namin kasi nagulat din kami," he said.

John surmised that Jason was angered by the cast constant teasing of the comedian's former girlfriend, Melai Cantiveros, one of the show's main cast.

"Sa amin sa Banana Split talaga asaran talaga kami. Inaasar ko si Jason na malaking ulo, inaasar niya na maliit. It's normal. I felt na I was the one available during that time," John said.

Jason reportedly left the venue with ex-girlfriend Melai Cantiveros.

In a separate television interview, Jason apologized to John and the "Banana Split" staff and he hopes to personally apologize to the actor.

"Humihingi ako ng paumanhin sa iyo. Sana patawarin mo ako sa nagawa ko kasi alam ko na may pinagsamahan tayo. Yun lang, sana mapatawad niya ako and ng pamilya niya." (Sunnex)
