All is not well between Kristoffer Martin and mother of his four-year-old daughter, Pre. 

This was made obvious with the actor reacting negatively on former sweetheart AC Banzon's interview about their split.

On Twitter, Kristoffer wrote: "Di lahat maaamo mo. Di lahat kakampi sayo. Kasi alam nila yung totoo."

Then in another: "Isa isahin mo sacrifices ko before versus sa mga merch mo. Mygahd."

AC replied back, "Isa isahin ko kaya kalokohan mo hahahahaha."

She reiterated, "Ikaw ang sumira sa’yo. Your actions. Not me."

Kristoffer surprised his fans last month with the announcement he's already a father. 

Though he revealed that he and the mother of his child are no longer together as "things didn't work out."

Not long after AC released statement about their split through PEP.ph.

According to her, Kristoffer ended their seven-year relationship just a day after he came back from a lock-in taping.

She noted their breakup was not a mutual decision; and that she was shocked when she found out the actor's statement about their split.

"Maybe it didn’t work out towards the end… for him. I tried to work it out po talaga. As in I chased after him. Siyempre, given the situation na hindi lang naman po ito decision naming dalawa. There’s a child involved," she said.

Then at the latter part of the interview, AC revealed how she felt that Kristoffer might have fallen for someone else during his lock-in taping. 

“If you are asking po if he admitted, yes po. But after the breakup na po. I mean, mga more than a week after (later)," she said, adding the actor didn't name the woman.
