Battle of the behinds! Pregnant Kim Kardashian bumps into bootylicious pal Serena Williams in London... as the tennis ace strokes her growing baby bump

The bootylicious ladies embraced on the street outside Harrods and Kim placed her hands on her hips as the World Number One tennis player rubbed her baby bump.

Take your style up a tier in Kim's ruffled skirt
They say if it ain't broke don't fix it and Kim Kardashian has stuck to this mantra faithfully. The Selfish author rocked her signature look in a black, plunge neck top and form fitting skirt by one of her favorite brands, Givenchy.
The reality star added a pair of perspex sandals and dark shades to complete her racy ensemble.
We love the girly asymmetric ruffle along the waistline of Kim's form fitting number that can easily transition from day to night. Dress it up with a floral print blouse and classic black pumps for the office.
