A former policeman, a socialite, a boxer, a glamour model and a mother and daughter complete the show's launch line-up for this year.
First to go in on last night's show was Gina Rio, a 24-year-old socialite who once lived in London's The Savoy hotel for months on end and whose parents apparently give her a £10k-per-month living allowance.
She is in a relationship with rapper EcKsell. Unsurprisingly, she was booed mercilessly by the crowd gathered at the Elstree compound.
Next up was Daniel Neal, who has just quit his job as a policeman. He had specialised in child abuse cases and had been working on Operation Yewtree.
The handsome 33-year-old, who is gay and in a relationship, received a positive reaction from the audience - as well as from host Emma Willis.
Third to enter the house on the second night was Irish glamour model Hazel O'Sullivan. The newly single 24 year old was revealed to be packing 10 bikinis and six bottles of fake tan.
Next came 28-year-old professional middleweight boxer Daley Ojuederie, who spoke movingly in his VT about his experience of growing up in foster care and who was applauded by the crowd.
The last two HMs to go in were a Big Brother first - a mother and daughter.
Jackie Travers (mum, 59) and Charlie Travers (daughter, 26) will be included as separate housemates - although they did chat with host Emma and enter the house together.
Dance instructor Jackie's funky moves in her VT were the highlight of the night for many viewers.
Sam still appears to be the bookies' favourite to win - although Daley is not far behind him on 4/1 with some bookmakers and Dan is on 7/1.
