There's no doubting the similarities between Katie Holmes and Victoria Beckham's new designer fashion campaigns - but who inspired whom?

Posh works her famous pout as she poses in lingerie in the latest ads for Emporio Armani, while Tom Cruise's missus appears to be channelling her former best pal as Miu Miu's leading lady for their Spring/Summer 2009 collection.

Although the ex-Dawson's Creek star keeps her clothes on, Katie's 'pob' hairstyle and dramatic eye make-up are almost identical to that of self-proclaimed style icon Victoria.

Katie even brought in the same world-class photographers Mert and Marcus that snapped Victoria's Armani campaign for her own shoot!
