MANILA -- JM de Guzman has apologized to his "Kung Paano Siya Nawala" co-star Rhian Ramos after the actress became the target of online bashing.

The bashing allegedly came from some fans of de Guzman and his rumored girlfriend Barbie Imperial, who were not happy with reports romantically linking Ramos to the actor after they worked together on the movie.

"Stay strong, alam ko medyo masakit na. I'm sorry. Ingat lagi kaibigan," de Guzman wrote in an Instagram post, as he thanked Ramos for her friendship and help.

"Salamat sa malupit na journey na makatrabaho ka. Sa pagkakaibigan na pinakita mo at pagiging totoo, salamat ng marami. All I have for you is respect at malasakit at alam ko ganun ka din sa 'kin. Salamat nakatrabaho kita. Salamat sa talento at inspirasyon. Tibay mo. Salamat sa tulong," de Guzman wrote.

Ramos responded to de Guzman's post and stressed that she will always be there to support him.

"I always appreciate how you always come out of pain stronger, smarter, and better. Don't ever lose that about you. But if you ever need an extra push, you know I'll be there for you. It ain't easy, but thank you for the friendship and thank you for this," she said.
