The company is keen to net the TV and radio presenter as part of its 'morning managers' programme, designed to drive sales of its breakfast-coffee portfolio. Ross is currently considering scripts for the campaign, according to an insider.
The ads, which will be created by McCann-Erickson, are expected to break early next year.
Ross would be the latest in a long line of celebrities to promote the brand, following fashion experts Trinny and Susannah and Capital Radio DJ Johnny Vaughan.
A Nestle spokeswoman refused to comment on the speculation, but said that it did not plan to replace Trinny and Susannah and that the relationship is 'working well'.
The plans for the activity come as the take-out coffee market continues to grow; at-home coffee consumption fell by 10% between 1998 and 2003, according to Mintel.
