Celebrity Big Brother kicked off with a fantastic performance from ex-EastEnder Natalie Cassidy who was forced to flirt with X Factor reject Frankie Cocozza to fulfil her first secret mission.
Natalie, best known for playing Sonia in the BBC One soap, was told to "kiss Frankie on the lips" and to tell him she likes younger men, by a mischievous Big Brother in her earpiece.
Frankie had arrived on the show promising to "sh*g in the house" and to a lot of boos from the crowd, but Natalie did not seem quite what he had in mind.
The disgraced 'singer' was thrown out of this year's X Factor after a drugs scandal and will now celebrate his 19th birthday in the house.
He told Big Brother host Brian Dowling he's "not fussy" about which women he'll get with, which is perhaps a relief for Natalie, who's being forced to use cheesy chat-up lines on the randy teen.
The other housemates who joined the Channel 5 reality show included Reservoir Dogs star Michael Madsen, who arrived wearing a cowboy hat, claiming he "knows f**k all about Big Brother" and stating that he imagines it will be "like rehab without a doctor".
Next up, Pineapple Dance Studio's Andrew Stone entered the house, after previously guest-starring on the show, and Hugh Hefner's ex-girlfriends, Playboy bunny twins, Kristina and Karissa Shannon strutted their way in to the house in £7,000 stilettos, instantly asking "where's the drinks?" as Natalie and Andrew gawped at their pins.
Welsh rugby star Gareth Thomas and his "fiery temper" then joined Britain's most talked about Bungalow, along with Nicola McLean who's had "a little spat" with Natalie before.
For some reason Marcus Bentley decided to tell us glamour model Nicola has brought in 14 pairs of shoes but only 7 pairs of knickers, while Big Brother instructed Natalie to continually embarrass herself by repeating that she's "cool" with Nicola now.
Taking after his ex-girlfriend and fellow TOWIE star Amy Childs, Essex chap and ladies man Kirk Norcross joined the house to "party". Followed shortly by someone who looks like his ideal woman Kim Kardashian - Georgia Salpa, one of the first ever FHM High-Street Honeys, who "works for one hour a day".
Natasha Giggs, who's famous for having an affair with her brother-in-law footballer Ryan Giggs, entered the house, predictably wanting to "get her side of the story across" and to lots of boos from the crowd.
Next came a blast from the past in the form of So Solid Crew member Romeo Dunn, who arrived to give the ladies some eye candy (and remind us that he's still around).
Loose Women star and former Corrie lass Denise Welch was the last star to enter the house, rounding off a highly-entertaining first episode of Celebrity Big Brother 2012 with her Ab Fab style fur coat and promises to get in the hot tub with the "young ones".
