JM de Guzman seems like he has an ax to grind against fellow actor Enrique Gil.

De Guzman on Friday challenged the "Forevermore" star to a slugfest.

"With all due respect to Enrique Gil's friends, fans and family. I would like to challenge to a one on one amatuer (sic) mixed martial arts match any place any time, " de Guzman said in an Instagram post.

"I'll give you time to prepare. Man up. Face me. (reply to my text messages please.) thanks brother.: @enrique17," he added.

The Instagram post has since been deleted but it remained on de Guzman's Twitter feed.

Amid rumors about their falling out, de Guzman earlier posted a cryptic message for Mendiola.

The 27-year-old De Guzman shared to his followers a sketch of Mendiola with the caption: "I don't draw. Finding it hard to remember the last time you smiled. Thank you [Jessy Mendiola] for everything."

Rumors about their breakup stem from a series of lengthy notes De Guzman posted on his Instagram page, where he mused about heartache, love, and online critics.

Mendiola was also involved in a drunken incident with Gil during the September 4 flight of some Kapamilya stars to London.
