Caggie, who starred in MIC in the first, second and third series, has stepped away from the limelight in recent times but was happy to pose for pictures at the bash.
Wearing a long grey coat and stylish shoe-boots, Caggie clutched a colourful handbag in her left hand as waiting photographers snapped away.
The singer/songwriter had tonged her blonde hair into big culs and she accessorised with a statement gold necklace.
The event was held by Magnum to celebrate the ice cream brand's 25th birthday and other guests included fellow ex MIC star Kimberley Garner and fashion designer Henry Holland.
Since leaving MIC, Caggie has been busy running her own fashion label, ISWAI, and her outfit was actually from the collection.
Caggie showed off her getup, which was hiding underneath her coat when she arrived, in an Instagram photograph taken once inside the party - and by this point she was all smiles!
Meanwhile, earlier today we revealed when the new series of Made In Chelsea would be airing - click here to find out!
