US Harper's Bazaar aren't the only ones releasing behind-the-scenes videos from their September issue cover shoot. Last week US Vogue released this video with Lady Gaga.

Granted, the video doesn't quite match up to Bazaar's sit down interview with Gwen Stefani. On the flip side, Vogue do offer up Marc Jacobs fluffy hats, elf shoes and Gaga doing her best Beyoncé hair-flicking impressions while her aptly titled new song 'Hair' plays. What more could you want?
