Then 18 and 22, Janella and Elmo were launched as ABS-CBN’s newest love team. Elmo moved to the Kapamilya network from GMA-7 to be part of a new series called Born For You.
Here's what Janella said about her new onscreen partner: “He seems like a very nice guy. Parang gentleman naman siya. We haven’t really talked. We are all hoping na this is going to work. I just actually met him last week so wala pa kaming expectations. I guess naman mabilis kami magiging close dahil sa music nga. I think we are going to have bondings din. I’m sure naman by January, we are close na.”

Janella accused Elmo of physically hitting her twice in her tell-all interview for The Philippine Star. According to Janella, the second time he hurt her happened during a party hosted by her friend. She also revealed that she fought back by slapping Elmo because she felt “disrespected.”
“For two years, I focused on Elmo and myself. This time, I am giving more attention to myself. He hurt me and I cannot, can never tolerate that,” Janella declared.

While Elmo and members of his family have not yet issued a statement regarding the matter, it was noticeable how Elmo's mom Pia Magalona shared a link about Borderline Personality Disorder on Twitter and said: "In borderline personality disorder, devaluation often alternates with idealization. They may shift from great admiration for a loved one—idealization of that person—to an intense anger or dislike towards that person—devaluation of that person."
