The 20-year-old had disappeared from the public eye since India secured the one-day title in Mumbai on Saturday, beating Sri Lanka by six wickets - raising fears among her fans that she only made the pledge for publicity.
However, breaking her silence via social networking site Twitter, Pandey said she is still going ahead with her plans to go nude - and hinted that details are already being ironed out for the event.
She wrote: 'Thanx a Lot All for ** Support!! I am Still on with My Commitments Stay TUNE

Later on Monday, Pandey added: 'Once Steve Forbes said "A promise made should be a promise kept." so guys soon will complete my promise just Wait n watch. [sic]'
Until then, the model's only public statement since India's victory had been a short message saying she was 'on cloud nine'.
Pandey also referred journalists who have apparently been badgering her for interviews and comment to a previous non-committal open letter to the Board of Control for Cricket in India (BCCI), two days before the final.
In that letter, the swimwear model said she would give the Indian team the choice of whether she should strip for them privately or in a public place.
However, she urged them to arrange for any open show to be staged abroad - preferably in Paris - to avoid the potential for outrage among traditionalist Muslims and Hindus.
