Nobody gets between Rachel and her $500,000!

She may be one of the most annoying HouseGuests in "Big Brother" history, but there's no doubt Rachel Reilly deserved to win Season 13 last night -- and she did just that.

While Rachel, Porsche and Adam went into the finale as potential victors, Adam was the first to go, leaving the two ladies to face the jury.

Shelly's tie-breaking vote sealed Rachel's fate as winner.

You may hate her ... but with four Head of Household victories, 2 Power of Veto wins and a fiance who was evicted from the house ... twice ... the feisty red-head really played the game.

Are you happy with the winner? Sound off below!
