MANILA - The teen housemates of the ongoing season of "Pinoy Big Brother" couldn't believe their luck when they got to meet Angel Locsin, Sam Milby, and Zanjoe Marudo.

Take Maymay Entrata for example, who immediately screamed in joy as Marudo entered the room. Marudo, along with his "The Third Party" co-stars, were pretending to be doctors and were tasked to do a routine check-up on some of the housemates.

The Cagayan de Oro native lost it when Milby and Locsin, whom she described as one of the sexiest women in the world, followed suit. "Sino ba ang magiging okay sa ganoong sitwasyon? Lahat ng nerves ko sumasayaw!" Entrata quipped.

Prior to Entrata, Yong Muhajil, Vivoree Esclito, and Kisses Delavin were all at a loss for words after meeting their newest celebrity guests. Delavin even got advice from Milby and Marudo, both former contestants of the reality show, about her crush problem over Marco Gallo.

"Ayaw mong agawin?" Marudo asked Delavin, who said that Gallo does not share the same feelings for her and has a crush on Esclito. "Gusto mo na lang ba na third party ka na lang forever?"
