The Twitter account also suggested Big Brother fanatics should keep an eye on the live feeds going forward because there will probably be another sneak peek of the new season soon.

Similar to prior Big Brother seasons, Celebrity Big Brother's twelve Season 2 houseguests have already moved into the Big Brother house and begun filming several days before the CBS reality series' January 21 premiere.

The Season 2 cast of Celebrity Big Brother has the five female houseguests: Singer and Braxton Family Values star Tamar Braxton, singer and The Real Housewives of Atlanta star Kandi Burruss, Olympic track and bobsled star Lolo Jones, actress Lindsay Lohan's mother Dina Lohan, and former WWE wrestler and Total Divas star Natalie Eva Marie.

The remaining seven male houseguests are actor and TV host Jonathan Bennett, actor and comedian Tom Green, actor and former O.J. Simpson houseguest Kato Kaelin, actor and singer Joey Lawrence, former Olympic swimming medalist and What Would Ryan Lochte Do? star Ryan Lochte, former White House director of communications and financier Anthony Scaramucci, and former superstar NFL running back Ricky Williams.

During the brief live feeds broadcast, it was revealed that Ryan Lochte won the first Head of Household competition of the season, according to the Los Angeles Times' Gold Derby website.

The live feeds, however, reportedly did not show whether Lochte nominated two houseguests for eviction following his big win, and the subsequent Power of Veto competition had yet to take place.

Celebrity Big Brother's second-season celebrities will spend about three weeks living in the Big Brother house, with over 80 HD cameras and over 100 microphones recording their every move 24 hours a day as they compete in competitions and try to avoid getting voted out of the house.

After Celebrity Big Brother's premiere on Monday, January 21 at 8PM ET/PT, CBS will air a second episode on Tuesday, January 22 at 8PM ET/PT.

As previously announced, the show will then air on multiple nights every week until its February 13 finale.

Longtime Big Brother host Julie Chen will resume her role on the celebrity version of the popular summer series.
