Pinoy Dream Academy winner Yeng Constantino opened the show with a song number with fellow PDA alumnus Eman Abatayo, in a rousing version of "Sikat and Pinoy", the official PBB Celebrity Edition theme song.
PBB hosts Toni Gonzaga, Mariel Rodriguez and Bianca Gonzales later wheeled in aboard a white stretch limousine.
After teasing audiences with clues about each new celebrity housemate, the three hosts finally revealed the identities of the first batch of housemates who were each blindfolded and led into the PBB House.
Everyone in this batch of celebrity housemates has a nickname, reflecting an aspect of his or her character. The four winning housemates will have his or her chosen charity as beneficiary.
First to enter the PBB House was "True Lover" Will Devaughn, a 25-year-old model with an interesting genetic mix: half-German, ¼ Pinoy and ¼ African-American. He is well known within the modelling circle and has been featured in various ads. Devaughn earned his nickname because he flew all the way to the Philippines to look for his long lost love, a young woman who already broke his heart twice. Chosen charity: Brave Kids Foundation.
17-year-old Megan "Princess of Charm" Young was up next. Young made her initial entry into showbusiness through "Starstruck", a teenage reality TV talent contest in GMA-7. She however is now more familiar to viewers as "Shane" a pretty social worker who was, until recently, a character on ABS-CBN's hit science fiction fantasy series "Kokey".
Young's character was written off the "Kokey" storyline to make way for her entry into the PBB House. Her character's exit from "Kokey" happened while the other characters were fleeing from the "bad alien" "Kurukuy". According to the script, Shane had to abandon her other companions and return to her parents.
Young earned her nickname because she "lives the life of a princess" who doesn' t do house chores. She admitted that she's not even used to cleaning and tidying up her own room--earning scoldings from her mother. She prepared for the PBB House by training herself to sleep alone, having been used to sharing a bedroom with her sister.
Young is very excited about her stay inside the PBB House, particularly because she heard that her big crush would also be in the house. The identity of her crush has not been revealed--yet.
Desirable Diva Riza Santos, is a 21-year-old Fil-Canadian beauty queen, the reigning Ms. Earth-Canada, in fact. She was recently featured on the cover of For Him Magazine (FHM) and is rumored to be a "very close friend" of singer Mark bautista.
Santos however has a tough side, too. Inspired by her grandparents who were survivors and veterans of the Second World War, Santos joined the military and is a member of the Canadian Cam Forces.
She admitted that she's officially "N.B.S.B", meaning, "No Boyfriend Since Birth." Her chosen charity is Bantay-Bata.
25-year-old Ruben Gonzaga is the "Komedyanteng Promdi" or "Comedian from the Province." Gonzaga, 25, is a Davao-based comedian, who popularized the "Budotz dance" there. He hopes to make it into the big league and help his family out of poverty.
Commercial model-turned actor Victor "Lonely Dream Boy" Basa admits to being an illegitimate child and wishes that he exerted more effort to find his biological father. Unfortunately, his father died before they could meet.
Basa admitted that he has been in and out of relationships for the past three years because he was afraid of being abandoned, hence the label "Lonely Dream Boy." He is supporting Ahon sa Kalye Ministries, Inc.
"Mom in Distress" Yayo Aguila was just 16 years old when she abandoned her acting career after she got pregnant with her first child with husband William Martinez. Now at 40, she is raring to make a showbiz comeback. She is best know for her love team with Martinez in the 80’s matinee idol movie "Bagets." Aguila said that she's been through a lot in her life, from drug use to her husband's philandering and depression.
"Wild Child" Baron Geisler is a 25-year-old actor known for his bad boy image. He admits to an alcohol addiction but is working on kicking the habit. He said his life went on a downward spiral of the death of his father. He had a few brushes with the law during his drunken phases and his house was even destroyed in a fire. Despite everything, Baron now wants to prove that he can be good.
"Brainy Babe" Marylaine Viernes and "Despised Babe" Jennifer de Silva are the "two-in-one housemates." This mean that their fates inside the PBB House are tied together. That is, if one of them is nominated for eviction, the other will share the same fate. Likewise if one of them is saved from eviction.
Viernes is a member of the 26K Girls of the popular game show "Deal or No Deal". This 21-year-old sexy bombshell earned her nickname for having both beauty and brains: she has a scholarship from De La Salle University.
De Silva, one the other hand, is a former member of the 26K Girls. De Silva was given her nickname because she decided to leave the group because of personality differences with the other members.
Viernes and de Silva will be informed of their "two-in-one status" on the show’s First Nomination Night next Saturday.
There's also a "surprise" housemate. He's Donald Geisler, chamption tae kwon do athlete and older brother of Baron. He had plans to work in the US but chose to stay in the Philippines to look after his son and misguided brother.
Geisler, who has been given the nickname "Good Brother" entered another part of the PBB House unknown to the rest of the housemates. What his presence will mean to the other housemates will be revealed in later episodes.
Four of the remaining housemates will enter the PBB House on Monday during Pinoy Big Brother Celebrity Edition 2, "UBER!" to be hosted by Mariel Rodriguez and Bianca Gonzalez.
