The supermodel - who hosts the hit TV fashion show - reportedly thinks an appearance from Britney would dramatically increase the program's popularity.
After meeting up with Britney at her 27th birthday party in New York's Tenjune nightclub this week, sources say Heidi is keen to ask the singer to appear on an upcoming episode of the series, which sees keen fashion designers compete to win a contract with a leading fashion store.
A source said: "Heidi is smart - she knows that Britney can do wonders for a show's ratings, there's been a lot of drama at 'Project Runway' - it would be huge for her to get Britney."
