Katie Price thinks "success is the best revenge".

The 33-year-old star - who has her own reality TV show, a range of equestrian wear, several books and MP3 player accessories among her many business interests - admits she loves what she does and will not stop until the public get bored of her.

She said: "I'm very ambitious. And success is the best revenge. Everyone who said, 'You can't do this, you won't do this. Ha ha you'll be finished.'

"It's not about money at all. I just love it. I'll carry on until people get bored. It can only end when people don't want it."

The former glamour model - who has three children, Harvey, nine, Junior, six, and Princess, four - is so busy with her career she admits she can't name all of the books she has released.

In an interview with Marie Claire magazine, she said: "Do you know how many books I've got out? I've got 40. I've got pony stories, I've got mermaids. From young ages to, well, women. I can't sit here and name them all, because I don't know all their names."

Meanwhile, Katie threw a party at London's Hilton Hotel on Saturday night (03.09.11) to celebrate her boyfriend Leandro Penna's 26th birthday.

Among the guests at the £10,000 bash were Michelle Heaton and several of the cast of 'The Only Way Is Essex'.

The party then moved on to Nylon nightclub at 2am and at one point Katie and Lauren Goodger shared a steamy kiss.

A source told the Daily Mirror newspaper: "Katie kept grabbing Lauren's face and planting smackers on her mouth. It all got a bit raunchy. Lauren was giggling and taking photos. Leo was looking on with his tongue hanging out. He loved it."

However, Katie was suffering on Sunday morning (04.09.11), admitting she had not got that drunk in a long time.

She wrote on twitter: "Omg biggest hangover ever its been ALONG time since I've had a night out drinking and boy do I feel it! happy birthday leo hahaha (sic)"
