Who Won 'Big Brother' 13?

Who Won 'Big Brother' 13? Rachel Reilly, a 26-year-old cocktail waitress from Los Angeles, took home the $500,000 grand prize last night on "Big Brother" over 23-year-old Porsche Briggs.

The redhead had started the season with her fiance, Brandon Villegas, with whom she had competed on the 12th season of the show.

When the finale began, three competitors - Reilly, Briggs and Adam Poch - remained. After winning the HOH competition, Rachel evicted Poch, electing to take newbie Briggs into the final round.

In the final round of the show, the seven jury members asked each woman two questions, which all the jurors had agreed on. After each of the final two women was allowed to make a final statement, the final vote was tallied.

"Rachel, you're lucky this is not a personality contest," said Daniele Donato, who voted for Briggs.

"I was a target since I walked through these doors," said Reilly.

"Oh, it's going to be a very hard decision," said her fiance Villegas, who may have made the difference for Reilly.

All tallied, Reilly got four of seven votes, winning the competition over new contestant Briggs. Shelly Moore, veteran houseguests Jeff Schroeder and Jordan Lloyd, and her fiance all placed the deciding votes.

On winning the $500,000 prize for "Big Brother" Season 13, Reilly told People: "I have no idea how this happened, but I fought my heart out this whole summer. It's crazy: Last summer I met my fiancé, this summer I won 'Big Brother'! This has changed my life.

Jeff Schroeder took home the "America's Favorite" Prize worth $25,000.
