The reality babe flaunted her curvaceous figure in a pair of skin-tight, high waisted jeans in a light blue hue at the event which drew in celebs such as CBB's Imogen Thomas and Nikki Grahame. And in spite of the persistent nip in the air, Marnie opted for a backless burgundy top that boasted a plunging neckline, giving the paps a glimpse of her enviable assets.
Staying true to her unique style, Marnie accessorized with an ultra chic bowler hat, clinging on to the summer with a Western-esque fringed bag and teetering on these peep-toe sandals which featured a KILLER platform.
Even though Marnie's shoes were much bigger, it was friend Melissa Reeves that took a tumble outside the London club on their way home, dragging poor Marnie with her. Ever the fashionista though, Ms. Simpson avoided an embarrassing wardrobe malfunction and left with her stunning hair and make-up completely in tact.
Earlier this week, Marnie set the rumour mill spinning once more when she took to Twitter to share an emotional Tweet and fans were quick to link it with the alleged relationship troubles.
Good pal and CBB star Chloe Goodman who was also in attendance at the celebrity bash cleared up confusion surrounding Marnie's sad Tweet, hitting back with: "This tweet was about her puppy Smith not Ricky ... Her puppy had a horrible accident @MarnieGShore."
Marnie retweeted Chloe's message to clear things up but she hasn't yet explained what happened to her poor pet pooch.
Fingers crossed he's on the mend!
