The blonde socialite stepped out in a form-fitting dress for the premiere of Machete Kills in Los Angeles last night (2 October).
With a below-the-knee cut and showstopping cut-out detail, Paris' dress was just the right side of sexy.
Look familiar? Nicole rocked the very same number just a few months ago!
The X Factor judge debuted the look during auditions in Manchester in June. With minimal jewellery and sky-high black heels, it was an almost identical get-up.
In true US starlet style, their dress is a high-fashion design by celebrity-favourite Herve Leger worth almost £5000!
We just can't decide who worked it best... Nicole's glossy ponytail looked super-hot while Paris got extra chic points for revealing a little less cleavage.
