Paul McCartney and Heather Mills both have appearances on US reality TV shows in the pipeline, according to a report.

Sir Paul has been approached to appear as a guest judge on American Idol in April, and could be paid £200,000 for 90 minutes' work if he agrees.

A source told the News of the World: "It would put him back on the box in the US."

Meanwhile, Paul's estranged wife Heather has asked producers of Dancing With The Stars, the US equivalent of Strictly Come Dancing, if she can be a contestant in the next series.
