The Atomic Kitten singer, 'Loose Women' panelist and American actor were joined by a host of other celebrities as they entered the reality show house in London for the UK vs. USA-themed series of the Channel 5 show this evening.
Speaking before she went into the famous house, Sherrie admitted she would be less than impressed if any of her fellow housemates decided to get up close and personal in front of her.
She said: "People having relations in bed next to me will annoy me, only because it has been so long I can't remember how you do it!"
Natasha, who has 11-month-old daughter Ella with 5ive's Ritchie Neville and sons Josh, 12, Harry, 10, and Alfie, 4, from previous relationships, confessed she was brining a memento along to comfort her when she starts to miss her family.
Asked what she was going to miss the most, aside from her kids, the 33-year-old singer said: "My bed! And the smell of Rich. I have made him wear a t-shirt and I've got it with me so I can have cheeky sniffs every night! That sounds weird! It's my man smell, I love it."
Meanwhile, Daniel, who is the younger brother of '30 Rock' star Alec Baldwin and older brother of former 'Celebrity Big Brother' housemate Stephen Baldwin, insisted he has no plans to push his religion on his fellow celebrities.
The 'Homicide: Life on the Street' actor, who was once alleged to have ran around a hotel screaming his famous family name while in possession of cocaine, said: "If somebody wants to talk to me about my relationship with God then great, I love to do that but I am not going to sit there and tell someone why they are going to hell. He [Stephen] is a little more bible thumper than I am."
Also on the line-up are US reality star Austin Armacost, who previously dated the designer Marc Jacobs, 'The Bill' actor Chris Ellison', 'Teen Mom' star Farrah Abraham, Hip Hop legend Fatman Scoop, TV presenter Gail Porter, 'The Apprentice' failure James Hill, former porn star Jenna Jameson and US singer Tila Tequila.
'Celebrity Big Brother' continues tomorrow night at 9pm on Channel 5.
