She's convinced she's the new Yoko Ono and admits her marriage may fail. At the tender age of 19 Peaches Geldof had packed in more drama than most of us would experience in a lifetime. Last night she made her mark on the Manhattan party scene in typical statement style, sporting a skimpy playsuit and blue-tinted hair. As she takes her personal brand of teen rebellion stateside, we look into the phenomenon that is Planet Peaches...

Without the distraction of anything as annoying as, say, a job, Peaches Geldof has been indulging herself in her true calling - as full-time rock chick.

It is not, she is quick to point out, nearly such an undemanding existence as it might seem.

First, there is all that personal grooming involved before she can head out of the door to face the ever-present paparazzi (she is wont to complain that she feels she must dress up to the nines at all times in case someone wants to take her picture).

Then, there is the hard bargaining to be done to snag herself a front-row seat at the most happening fashion shows on both sides of the Atlantic (anything less than runway seats would mean social death, darling).

And last, but not least, is the ever-present risk of coming a-cropper while wearing sunglasses indoors. All in all, it's no walk in the park.

Of course, you should not overlook the privations to be experienced while on the road with a rock band. And given that her new husband's group is not exactly a household name, to her immense irritation, Peaches has been finding that being a rock chick is not quite as glamorous as she'd been led to believe.

Pampered Miss Geldof, who, thanks to the enormous wealth of her father Sir Bob, has been used to a comfortable life in London, has had to slum it in the back of a grungy van as she tours the U.S. with wannabe rocker Max Drummey and his group Chester French.

No wonder she has been musing publicly on the chances that her marriage may not go the distance.

Admitting she rushed into the union three months ago with Boston-born Max, 19-year-old Peaches said: 'You can't ignore divorce rates. Every friend of mine has parents who are divorced. I didn't go into it with Max thinking: "This is going to last for ever." '

This might be for the best, considering that friends are whispering behind their hands that the fledgling union has already suffered several high-pitched bust-ups.

The problems, I am told, stem from the fact that Peaches has fallen out with David-Andrew Wallach - 23-year-old Max's partner in the little-known group - whom Drummey met when they were Harvard students.

Wallach, who has admitted to being annoyed that the sideshow of Drummey's out-of-the blue marriage has distracted attention from their music, is said to be at loggerheads with Peaches.

More importantly, Drummey, who was initially welcoming of the attention their Las Vegas wedding gave to his hitherto unknown band, is said by friends to be regretting hitching himself to the publicity bandwagon of the attention-seeking Peaches.

Friends say he told his bride in no uncertain terms that she was not wanted on the band's current tour of the U.S.

Given that they had known each other barely a fortnight when they tied the knot while on holiday at the beginning of August, perhaps someone should have warned the unsuspecting Drummey that it does not do to upset the very demanding Miss Geldof.

She was spitting blood, say friends. And it was not a state of affairs she was prepared to tolerate for long. Last week, she and Drummey were back together as the group travelled to a gig in Las Vegas.

But the rapprochement has not stopped Peaches describing herself - apparently with a straight face - as 'the new Yoko Ono' (an unintentionally hilarious reference to how Ono's relationship with John Lennon hastened the demise of The Beatles). All of which is typical of the fantasy world that is Planet Peaches.
Drummey, with his Monkees hairdo, is no John Lennon. Nor is his band - which is yet to release an album and has been on the receiving end of scathing reviews - on a par with the Fab Four.

Nonetheless, Peaches is said to be 'going ape' after being barred by her new husband and his cohorts from fulfilling her ambition of joining the group as a backing singer.

Anyone who has witnessed her previous caterwauling and cringemaking live singing - which was captured on YouTube during an impromptu gig at a basement club in London's Covent Garden earlier this year - will attest that Chester French's small coterie of fans have had a lucky escape.

But the headstrong Peaches is not one to be put off easily. She has told friends that after 'conquering London', she is ready to make herself a household name in the U.S., too.

Indeed, she has been telling friends she has travelled to Hollywood to discuss fronting her own show for a major U.S. TV network.

And she has been hard at work refining her American accent. Her conversation is littered with the words 'dude' and 'like'.

Witness a toe-curling video posted on Max's website last week in which Peaches, who fancies herself as a serious interviewer, questions her husband in a grating Valley Girl drawl as she operates a shaky hand-held camera.
