Gentlemen, I’ve seen them up close and personal and, boy, are those Bristols big and bouncy.

Watching her strutting her sultry stuff in 7in diamond studded stilettos and the world’s tiniest pink feathered thong, you might be tempted to write Jenna off as a dumb blonde who used to have sex on camera for a living.

Don’t be fooled by the Barbie doll exterior. Reportedly the most searched-for woman in the history of the internet, she is one tough cookie with her eye on total world domination.

Jenna’s dad is a former police officer. Her beloved mother, a Las Vegas showgirl, died before her second birthday.

So Jenna, now 34, grew up with one towering ambition – to tread the boards wearing nothing but rhinestones in a Vegas extravaganza, just like Mom.

It didn’t happen that way. Casting agents rejected Jenna. “They said I was too small and had braces on my teeth. That only made me even more determined.”

Jenna grabbed a pair of pliers, yanked the braces off her teeth and within six short months was earning $2,000 a night dancing. She’d shown them!

Sipping champagne and nibbling on a sandwich, Jenna shoots straight from the hip.

“Last year I sold my porn empire for $40million. I’m a businesswoman. I truly believe I’m not the most beautiful, or the most talented, but I am the smartest.

“I wasn’t going to be just a girl who took her clothes off for money. I was always in charge of my shoots. I owned my pictures. I charged big money.

“By 2001, I earned $60,000 a day filming and $8,000 per night dancing at strip clubs. I tried to restrict myself to five films per year and two weeks of dancing per month. I appreciated the business potential and I was in control of my destiny.

“After I sold the company, I tried being a lady of leisure – hanging out in my Hollywood mansion, buying out the whole of Dior, having lunch. It was fun to begin with, but I didn’t feel comfortable not challenging myself. I want to be able to lay my head down at night and know I accomplished something. I want to make things happen.”

What’s definitely not happening any more, ever, is Jenna having sex on camera. There’s no need – she only started in adult movies to get revenge on a cheating boyfriend and right now she just happens to be head over heels in love with ultimate fighting champion, Tito Ortiz.

I say “head over heels” because heels – the higher and pricier the better – play a big part in their sex life.

“I wear high heels to bed with him. I vamp it up. Sex with Tito is the best I’ve ever had. He makes me feel beautiful.

He makes me want to be Jenna Jameson in my real life, not just in public.” Of her last relationship, which has just ended in a bitter divorce, she says: “I couldn’t even be bothered to shave my legs before bed.” 

Jenna describes Tito as “the love of my life”, but how does he feel about millions of men all over the world being able to buy a DVD and see his girlfriend getting down and very dirty with other blokes? Not to mention Jenna’s bisexual past. She claims to have slept with 100 women and 30 men – and that’s just off-screen.

“Tito is extremely confident,” she says. He’d better be. Past boyfriends include Marilyn Manson and Pamela Anderson’s ex Tommy Lee.

“It’s OK. He’s his own man. He can move on from my past. This year we are planning to make babies together. He’d make a fabulous dad and I know I’ll be a fantastic mother.”

The question is how Jenna and Tito will find the time to make babies when she’s hell-bent on expanding her empire Jordan-style to include acting, singing, fashion and merchandising.

Jenna is also starring in  movie Zombie Strippers alongside Robert Englund, who played Freddie Krueger. It’s doing storming business in the States and premieres in the UK on May 24.

“American critics said I didn’t have to act. I’m a zombie playing a zombie. Let them say what they want. Let people call me a bitch if they want to.”

But, hand on heart, can she actually act? “Yes I can. I can do anything I set my mind to.

Even singing?  “Yes. I can sing. I can do everything. I am a superstar.”

Confidence like Jenna’s is dazzling.  “There is no stopping me. Nothing I don’t want to conquer. I know I’m capable of so many things.” What about eating lunch? Would she dare attempt that? Is Jenna, like so many famous women, sticking to a no-food diet? Far from it. Although she’s currently a tiny size zero, she truly doesn’t mind going up a few dress sizes.

“I’m small-framed. I’m about 5ft 6in and weigh around 7D stone. I train every day. I make sure I don’t eat fast food. But if I gain a few pounds, who cares? Tito’s a Mexican. He loves girls with great big butts. He’s most turned on by my big booty.’

Jenna is convinced that men prefer women with a bit of meat on their bones. “Flesh is sexy. Categorically. And I should know.”

Jenna’s plans to conquer the world are in full flight. Her denim line, JennaJeans, will be sold at Harrods. She’s starring in reality show I Love Jenna documenting every second of her passionate life with Tito.

Can she stand the thought of a camera crew following her 24 hours a day? “Bring it on, I’ve got nothing to hide.”

She’s also planning to bring out a make-up line. “I have lived most of my life in full make-up. To women who say they want to look natural, I say: ‘Oh puhleeze!’

“I’m a girlie girl. I adore false eyelashes, hair pieces, anything glamorous. Why shouldn’t other women have a chance to play around with the make-up products I love?’

She loves Jordan, too: “We’ve had parallel careers. I’d love to do a photoshoot with her.”

Jenna meets Jordan. Now that would be one for the history books.

With a kiss on the cheek, Jenna – most successful adult film star ever – bids me goodbye and strides off to yet
another empire building meeting.
