The former glamour model posted on Twitter at the weekend that she wants to sell the customised Vogue model car - which has the registration plate KPII HOT, a diamond encrusted clock worth £25,000, and aluminium wheels, exhaust and pedals - and called for her followers to express their interest in buying the vehicle, which she bought for a reported £100,000 in 2011.
Responding to her message, the BBC Radio 1 DJ said he was ''very interested'' in making the purchase.
However, Nick also faces competition in landing the vehicle from 'Geordie Shore' star Holly Hagan - but only if she can raise the necessary funds.
She tweeted: ''Omg I would love it wish I could afford it (sic)''
Katie - who drove the pink car away from her wedding blessing to Kieran Hayler on Friday (29.03.13) - had tweeted: ''I want to sell my pink range rover anyone interested?? I want to get a new car xx.
''For enquires about my pink range email email@example.com serious enquiries only please. (sic)''
