Did Aiko Melendez get into a fight with her 'Prima Donnas' co-star Althea Ablan?

The cast and crew of "Prima Donnas" witnessed a shocking confrontation between Aiko Melendez and Althea Ablan during their lock-in taping.

Fortunately, it was only one of the many pranks the talented group of actors have been pulling on each other on set.

In her recent vlog, Aiko can be seen confronting Althea for supposedly making a rude comment behind her back.

According to the actress, some of the crew heard Althea remark that Aiko was being "too loud" during taping.

"Kung may problema ka sa akin, sabihin mo, kasi ayaw kong makipagbastusan, kasi, ako okay naman ako sayo eh," Aiko told Althea.

Althea was visibly shaken while repeatedly trying to deny the accusation.

Aiko, however, did not let up. "Gusto mo kausapin ko mommy mo?" she even asked.

When Althea fell silent and was starting to tear up, Aiko suddenly yelled "It's a prank!" and the tension quickly cooled down.

Aiko's vlog also showed how she played a similar prank on another co-star, James Blanco.

Despite the troubling accusation that he was making comments about Aiko not memorizing her lines, the actor remained a complete gentleman and politely tried to clear up the misunderstanding.

Elijah Alejo also kept her cool when Aiko, with a little help from her friend and co-star Jillian Ward, also tried to pull a prank on her and failed.

This, however, was not the first time Jillian and Aiko had teamed up for another terrifying prank on their co-stars.

As seen in Aiko's earlier vlog, almost the entire cast of "Prima Donnas" turned frantic after Jillian "fainted" during filming.

The "Prima Donnas" family just wrapped up the final days of their lock-in taping.

In her new vlog, Aiko explained how pulling pranks on each other on set just showed how concerned she and her actors were for one another.

"Napatunayan ko do'n at napatunayan din ng mga tao na pagka may ganon na insidente sa set, totoo man o hindi, talagang sama sama kaming mga artista," she said.

"Natataranta, and we look out for each other, and napatunayan namin talaga ang concern namin sa isat isa," she added. —Margaret Claire Layug/JCB, GMA News
