"Direk, ayaw ko na," cried Kim Chiu, after she was playfully teased by her "It's Showtime" co-hosts over a special guest they had in Saturday's episode of the noontime show.

That person, of course, was Gerald Anderson, Chiu's ex.

Now both of them are already in a new relationship (Chiu is with Xian Lim, while Anderson is with Bea Alonzo), but that did not stop the likes of Vhong Navarro, Ryan Bang, and Billy Crawford from joking that Chiu seemed unusually irritable.

"Alam niyo ang OA ninyo guys," said Chiu, who quickly turned to the show's director, Bobet Vidanes, for help. "Alam ninyo, ang lala ninyo. Direk, inaaway nila ako."

Unfortunately for her, try as he might, he, along with fellow judge Ruffa Gutierrez, just could not resist joining in the fun.

Anderson was part of the judging panel for the segment dedicated to aspiring actors to promote his new movie, "Between Maybes."

The Black Sheep production, also starring Julia Barretto, is set to premiere this May 15.
