Introducing the other Geldof girl: Now Fifi Trixibelle hits the party scene

Her sisters Pixie and Peaches Geldof have developed a reputation as Boomtown Brats, but last night it was Fifi Trixibelle's turn to hit the London party scene.

The eldest Geldof girl made a rare public appearance last night at bash held at Kitts nightclub, where she was joined by flamboyant 'Queen Sloane' Henry Conway, the elder son of disgraced Tory MP Derek Conway.

Across town Peaches was at Bungalow 8, where she stayed until 3.30am with Horror frontman Farris Rotter.

Career girl: Fifi landed a job with a London PR firm last year

While her teen sisters have become limelight loving girls about town, 24-year-old Fifi has largely avoided the spotlight they've so eagerly pursued.

Last year, she quietly landed a job at PR firm Freud Communications where a source said at the time: "Fifi is working on talent and special projects.

"She's getting on really well."

But she did have a brief flirtation with life as a wild-child.

In 2002, she was arrested for being "drunk and incapable" after a drinking session in London's West End.

She was put into cells to sober up following her altercation with the police in the early hours the morning after she was found alone, slumped in the street and "clearly very worse for wear".

Her arrest came nearly two years to the day that her mother, Paula Yates, died of a heroin overdose at 41.

For a time she was a familiar figure in Chelsea wine bars but since that brush with the law, Fifi has kept a low profile.

She has long moved out of the self-contained flat she once shared with Peaches that was attached to the home of Sir Bob Geldof's and his French actress girlfriend Jeanne Marine.

Sir Bob, who has also raised Tiger Lily, Paula Yates's daughter to Michael Hutchence, once described his eldest as a "great companion, fantastic fun, a gorgeous girl, though the most like me in that she can also be unco-operative and surly."

"She walks like me, scowls at people like I do, is iconoclastic to a fault".
