Big Brother 4 (US), also known as Big Brother 4: The X-Factor is the 4th season of the broadcasted edition of Big Brother (U.S.). It aired on July 8, 2003, and ended on September 24, 2003, lasting 82 days. This season's winner was Jun Song, who beat her on-off ally Alison Irwin in the Final 2 by a 6-1 vote.

The season is characterized by the complex social dynamics between the houseguests and their ex-lovers, the rise and fall of the majority alliance Elite Eight, Scott's ejection as a result of his ex Amanda being in the house, the power shifts and eviction blindsides throughout the season, the introduction of the Golden Power of Veto and jury sequester, the successful execution of the floater strategy by both Jun and Alison and the subsequent decimation of all warring alliances.

Major alliances of this season include the Elite Eight (Dana, Alison, Jack, Erika, David, Jun, Nathan & Scott), the Three Stooges (Justin, Jee, Robert) which extended to Jun to make the Dream Team, and the Girl Power group that Alison, Jun, and Erika formed near the end.

Twists/Changes

• Golden Power of Veto: Introduced in the previous season as the last veto competition of Big Brother 3, was the Golden Power of Veto, was now the mainstay veto for this, and future seasons.

The Exes

• The X-Factor: While 8 Houseguests entered the house initially, they were told that 5 of the remaining Houseguests were ex-lovers with one of the 8.
• Power of Veto Played Before Nominations: In Weeks 7 and 8 the veto competition happened before the nominations ceremony was held.
• Diamond Power of Veto: The Diamond Power of Veto was introduced as the final veto power in the final 4. It allowed the holder to save a nominee from eviction and name the replacement.
• Sequestered Jury: A Jury of seven who would decide the outcome of the game. When there were nine players left in the game, the evictees formed the jury. The sequestered jury was introduced after many outcry among fans when Danielle Reyes lost Big Brother 3 arguably due to evicted houseguests seeing her diary room sessions.

However, she betrayed the alliance after she nominated two of its members, Alison Irwin and Jack Owens, Jr., for eviction. Dana exclaimed that she wanted Alison out of the house, as she thought she was "coming after" her. Shortly before the Veto competition, Nathan Marlow decided with Alison that if he were to win the Veto, he would use it to save her. At the Veto competition, Nathan was victorious. At the Veto ceremony, Nathan decided to remove Alison from the block. This angered Dana greatly; so, in retaliation, she decided to nominate Nathan's ally David Lane.

At the Head of Household competition, Jee Choe was victorious for a second time. For the first time ever, the Veto competition was held before the nomination ceremony. At the Veto competition, Julie gave each of the houseguests dilemmas in the diary room. The houseguest that accepted one of the dilemmas would win the Power of Veto. All houseguests rejected the first two offers. However, Jee accepted his third offer which meant that he won the POV. This meant that all houseguests, except for himself, would have to eat only PB&J for one week. Jee decided to nominate Erika Landin and Jack Owens, Jr. for eviction. His plan was to break up the close relationship that they had formed with each other. However, his main objective was to evict Erika. Jack was evicted from the house.

At the Head of Household competition, Jun Song was victorious. Straight after Jun was crowned HOH, she was called to the diary room and told that she would be leaving the house to attend the MTV Music Video Awards. Once again, the Power of Veto competition occured before the nomination ceremony. The objective of the Veto competition, was to discover where Jun had gone. The houseguests were provided with clues to help them figure out where Jun was. If none of the houseguests correctly guessed where Jun was, then Jun would win the Veto. Alison Irwin guessed correctly and won the Power of Veto. After Jun returned to the house, she was told that Alison had won the POV. She decided to use this as a way to hide the fact that she and Alison had an alliance. So she nominated Alison and Jee Choe for eviction, knowing that Alison would save herself with the Veto. At the Veto ceremony, Alison removed herself from the chopping block. Jun chose Robert Roman as the replacement nominee. In the previous week, Jee angered many of the houseguests after he put the house on a PB&J. This ultimately resulted in Jee being evicted by a unanimous vote.

Alison won the first and only Diamond Power of Veto of the season; this meant that she had sole power over who was evicted. At the live Veto ceremony, Alison decided to remove herself from the chopping block once again. This meant that Alison had to evict either Jun or Erika.
