"Big Brother" returned last night -- and so did some of the show's most familiar faces!

For "Big Brother 13," only 8 new cast members were introduced at the top of the show ... leaving the housemates wondering who else would be joining them.

About halfway through the episode, they got their answer: 3 duos from past seasons!

Who were they? Brendon and Rachel from Season 12, winner Jordan and Jeff from Season 11 and winner Evel Dick and daughter Danielle from Season 8.

Happy they're back? Wish they had picked someone else? Sound off below!
