Ray J has entered the "Celebrity Big Brother" house. The "Sexy Can I" rapper boasts about his infamous sex tape with his ex-girlfriend Kim Kardashian within seconds of his grand entrance on the 19th season of the hit Channel 5 show.

Ahead of entering his temporary Hertfordshire house, Ray says in his introductory video tape, "You might know me for my music, TV shows and my d**k! Put some money in my pocket, you're still j***ing off to the sex tape! Enjoy!"

Rumor has it, Ray is getting a record-breaking payday for joining "Celebrity Big Brother". According to TMZ, the U.K. TV show is paying the rapper $1 million to do the show and giving him up to $30k for accommodation.

While Ray's manager, David Weintraub, would not comment on the deal, he said the rapper's looking to buy a flat in the luxurious Mayfair district.

A source tells The Sun, "Bosses are over the moon with how the negotiations are going. Kim is one of the biggest celebrities in the world and they were never going to get her but booking Ray J means they'll get someone with proper insight into what goes on behind closed doors. He was right by her side as she shot to fame because of their sex tape so they are hoping he will talk openly about their relationship and reveal lots of new things about her while in the house."
