H&M’s Holiday Stars–Pop singer Lady Gaga and crooner Tony Bennett already worked on an unexpected album collaboration together called “Cheek to Cheek”, and now they will both star in H&M’s holiday 2014 advertisements. The Swedish retailer announced the news earlier today along with a behind the scenes image which shows Gaga with a curly wig and Bennett in a suit. Look out for the H&M holiday campaign in November.
