Me, pregnant? Kim Kardashian conceals her baby bump under a feathered top at the Topshop opening party in West Hollywood, California on Wednesday

So many parties so little time: Kanye did not walk the carpet at the Topshop event but did go with Kim to the Tommy Hilfiger new West Coast flagship opening afterparty later

The pregnant star had jetted in from Rio de Janeiro on Tuesday and she was back to her celebrity duties the next day.

Not one to let pregnancy stand in the way of fashion, Kim combined the dress turned top with leather pants to hide her bump.
She teamed the ensemble with black suede pumps and kept the look unfussy by wearing her hair sleek and loose.
Kanye also donned leather pants to match his girlfriend for the evening.
The rapper - who was by his pregnant partner's side when they attending the Tommy Hilfiger West Coast flagship store opening after Topshop's bash  - added an unusual patterned t-shirt and a pair of sneakers to his outfit.
