(L-R) PBB hosts Bianca Gonzalez, Toni Gonzaga, and Mariel Rodriguez greeted the housemates in the PBB eviction hall before they went inside Big Brother's house. The celebrity housemates will remain inside Kuya's house for 10 weeks.

The glamorous hosts toured Big Brother's house and found elegant furnishings, such as crystal chandeliers and murals by famous painters Boticelli, Leonardo da Vinci, and Michaelangelo.

Pinoy Dream Academy Grand Star Dreamer Yeng Constantino and Eman Abatayo sing their rock version of the PBB theme song "Sikat ang Pinoy." The original song was previously performed by Toni Gonzaga and Sam Milby.

A two-level grid was set up in the eviction hall to conceal the identities of the celebrity housemates.

The first housemate to be introduced to the public was "The True Lover" Will Devaughn, 25. The German-Afro-American model chose the Brave Kids Foundation as his beneficiary. The Big Four will receive cash prizes and their chosen charitable institution will also receive cash prizes equal to their winnings.

Will Devaughn became recognizable through his commercial for a popular hamburger chain. He also did hosting stints for Men's Room on Studio 23 and for the recently concluded Search for the Next White Castle Girl on ABS-CBN. Beside Will are Toni Gonzaga (left) and Bianca Gonzalez (right).

"The Princess of Charm" Megan Young, 17 (middle), is said to be living a fairy tale. Will she survive the rigors of living with strangers while under the watchful eyes of Big Brother? The StarStruck 2 Avenger signed up with the Kapamilya network earlier this year. Since then, she has starred in Abt Ur Luv and the sci-fi show Kokey. Her chosen charity is the PREDA Foundation, which addresses the needs of women who experience sexual exploitation.

FHM October 2007 cover girl Riza Santos (middle) is "The Desirable Diva." The 21-year old model represented Canada in the Miss Earth 2007 competition and now she's the Philippine ambassador to Canada. Riza joined the military to work as a medic. She chose Bantay Bata 163 as her beneficiary.

Ruben Gonzaga, 25 (middle), is "The Komedyanteng Promdi" who is expected to bring his own brand of humor to Big Brother's house. He is from the province of Davao, where he appears in ABS-CBN Davao and in local stage plays. The quirky Ruben popularized the "Budots" dance in his hometown. If he wins PBB Celebrity Edition 2, the Cosugian Home for the Aged in Davao City will also receive a corresponding cash prize.

Victor Basa, 22, plays Stick in the youth-oriented show Abt Ur Luv.  

The commercial model was chosen as one of Cosmopolitan's Celebrity centerfolds last year. Victor is part of the ASAP Coverboys and has appeared in the movie Crazy For You. "The Lonely Dream Boy" has his own set of family problems that he needs to deal with as he socializes with the other housemates.

Former Bagets star Yayo Aguila (middle) makes a comeback on primetime television with her entry in Big Brother's house. The "Mom in Distress" met her future husband William Martinez on the set of Bagets and they now have four children. Can Yayo bear to be separated from her kids for 10 weeks?

Baron Geisler (middle) had his facial scars removed by plastic surgery last July 17 but some were still visible when he was presented to the public last Sunday. The 25-year old actor got his scars during a bar fight in Pampanga a couple of months ago. Baron was launched as part of Star Circle Batch 5, but when his father died he turned to drinking in an attempt to escape grief. He entered a detox facility for 10 days, as his mother had suggested. Will Big Brother be able to tame "The Wild Child"?

One of the 26K girls of Kapamilya Deal or No Deal has entered Big Brother's house—Marylaine Viernes, "The Brainy Babe." The 21-year old stunner is actually a scholar at La Salle University and was part of the school's pep squad. She received a Palanca award for her Kabataan essay in 2004. As the spokesperson for the Advocates for Youth (A4Y), she naturally chose this group as her beneficiary.

Marylaine Viernes is paired with a former 26K girl, Jen Da Silva (not in photo). A two-in-one housemate will be playing together as if they were one person, if one gets nominated, the other is automatically nominated as well. Jen is dubbed as "The Despised Babe" because she often picks fights with other people, including some of the 26K girls. Will Marylaine and Jen get along inside Big Brother's house?

Donald Geisler (middle) is the older brother of Baron Geisler. He is also a two-in-one housemate, which means if Baron is nominated for eviction, Donnie will also be nominated, and vice-versa. The taekwondo champ and member of the Philippine Team won seventh place in the Athens Olympics. The 28-year-old athlete chose the KIDS Foundation as his beneficiary.

The lovable alien Kokey joined Toni Gonzaga in lighting up the life-size Christmas decorations located in front of the ABS-CBN main entrance along Sgt. Esguerra, the ELJ Building lobby, and the PBB house. Afterwards, fireworks lit up the midnight sky to welcome the housemates.

Although it's only the middle of October, Big Brother wanted the housemates and the viewers to feel the Christmas spirit, which is why a huge Christmas tree is set up inside the eviction hall. Inside Kuya's house, a false fireplace sits in one cozy corner.

Toni Gonzaga announced the prizes to be received by the Big Four. The 4th celebrity Big Placer and his/her chosen charity will each win P200,000, while the 3rd Big Placer and his/her institution beneficiary will receive P300,000 each. The 2nd Big Placer and his/her charity will both win 500,000, and this edition's Big Winner and chosen charity will each rake in a whopping P1,000,000.

The Celebrity Big Winner will also receive a Chateau Valenzuela condominium unit, a Sony Bravia and a business franchise from Goodah.

Ang Kapitbahay ni Kuya, Mariel Rodriguez, is sad that her show PBB Uplate has been removed but she is excited about hosting Über, which airs daily at 5:30 pm. "Über" is the German word for "Super!"

Bianca Gonzalez, ang dating boarder ni Kuya, recalls her stint inside the Big Brother's house. She was part of first batch of Pinoy Big Brother Celebrity Edition wherein she became close to Zanjoe Marudo despite being committed to director Lino Cayetano at the time.
