Another year, another star-studded (well, perhaps "star" is subjective) season of Celebrity Big Brother.

On Tuesday evening (Aug. 1), host Emma Willis introduced the roaring live studio audience, and the globe at large, to the cast of #CBB Season 20 in this season's two hour-long premiere. This time, the celebrity housemates will bicker, cry, emotionally manipulate and stealthily seduce their way to the finish line for a chance to win £50,000, which will be donated to the charity of their choice.

Who, exactly, made it to the house to play for the win on this season?

Why, only a smattering of ex-reality stars, former pop divas, controversial mediums – and one rather iconic blonde American YouTuber best known for her self-funded music career and kitchen floor breakdowns.

And the CBB contestants are, in no particular order:

- Shaun Williamson, best known for playing Barry Evans in EastEnders
- Sarah Harding, best known as one-fifth of Girls Aloud
- Sam Thompson, best known as a cast member on Made In Chelsea
- Derek Acorah, a psychic medium best known for Most Haunted
- Marissa Jade, best known for Mob Wives
- Sandi Bogle, best known for Gogglebox
- Chad Johnson, best known for The Bachelorette
- Jemma Henley, best known for Ex on the Beach and Signed by Katie Price
- Helen Lederer, comedian best known for Naked Video and Absolutely Fabulous
- Trisha Paytas, best known for her YouTube channel
- Kathik Nagesan, best known for The Apprentice UK
- Paul Danan, actor best known for Hollyoaks
- Brandi Glanville, best known for Real Housewives of Beverly Hills
- Jordan Davies, best known for Ex on the Beach and Ibiza Weekender
- Amelia Lily, pop singer and X Factor UK Season 8 finalist

The competition is now off with a bang, with Shaun being tasked by Big Brother to act increasingly nervous in front of the other housemates. He failed, resulting in being forced to make a Killer Nomination: he chose Marissa to be the first up for an eviction vote by the public.

Trisha, meanwhile, is busy asking everyone in the house why they're famous — and investigating who is uncircumcised.

Buckle up.
