MANILA -- Miss International 2005 Precious Lara Quigaman visited the "Pinoy Big Brother" house on Monday to teach the female housemates on how to act like a beauty queen.

Aside from walking and smiling like a queen, Quigaman taught them how to be confident despite pressure and criticism.

But while doing the exercises, Kisses Delavin, an amateur beauty queen in her hometown, suddenly broke down when Quigaman started pointing out how "chubby" she is.

Quigaman later on apologized to Delavin and the other female housemates for what she did, adding that it was also hard for her since she also went through all of those when she was starting out.
