The glamour model's locks looked an unsightly mess as she was seen leaving a friend's home in London last night.
Heaped into a BRITNEY-esque bun on top of her head, Katie's extensions were clearly visible.
There also appeared to be a noticeable change in colour between the roots and the hair pieces.
Katie's not had a great run of form with hairdressers, most recently threatening to sue a top Hollywood hair salon after a botched £11,000 hair extension job.
Katie - aka JORDAN - jetted 3000 miles to the States last December to see Lea Journo, one of the area's most in-demand coiffeurs.
However she claims the expensive treatment - which took 48 hours, over a period of five days - left her hair so damaged that she then spent £45,000 trying to sort it out.
After visiting a pal, Jordan was driven home by toyboy LEANDRO PENNA.
While her hair's condition is deteriorating, their romance is still going strong three months after meeting at SIR ELTON JOHN's post-Oscar party.
