Kim Kardashian would like to leave her sordid past behind, but the sex tape that launched her career as a celebrity will not go away. Sales of the tape soared riding a wave of hype from her wedding to NBA star Kris Humphries.

Kim was a nobody when she made the sex tape with former boyfriend hip-hop singer Ray j. Four years ago, in February 2007, it suddenly leaked onto the Internet, and Kim became an overnight sensation.

She was offered a reality show by E! Entertainment, and her career as a celebrity skyrocketed, until she became a major brand unto herself.

Her wedding was the culmination of her marketing career.

Kim is estimated to have made as much as $10 million from her wedding to Humphries last weekend, although exact figure is hard to come by and it may be much less.

She did however, sell exclusive rights to photos of the wedding for as much as $1.5 million to People magazine.

But Kim wasn’t the only one making money off her fame. More than two million viewers were drawn to the web site that sells her sex tape “Kim Kardashian Superstar,” up from normal traffic of about 300,000 viewers.

Irish viewers proved to be the biggest clientele, paying $50 to watch the footage for a month on the web, according to gossip site TMZ.

The tape runs for nearly 100 minutes, including more than an hour of new footage and even a ranting voicemail Kim left for Ray after the tape was leaked.

Despite suing Vivid Entertainment over control of the tape, Kim ended up cutting a deal for $5 million. Kim also gets a cut of sales.

Now, she says she regrets doing the tape and was “devastated” when the explicit footage became public. Others contend that she always intended to sell the tape and make it public.

Momager Kris Jenner has said that Kim needed a payday while she was shopping around her reality TV program.

While Kim can’t control access to the tape or reports about it, she was able to prevent E! Entertainment reporters from discussing or mentioning the tape.

Saturday’s ceremony, held on a private 11-acre estate in Montecito, Calif., sparked 22 complaints, mostly from neighbors irate loud music and helicopters overhead, police spokesman Drew Sugars told the Associated Press.

Kim’s first tweet following their big day was simply: ‘God is good!!!!!’
