The cute youngster escorted his mum down the runway, helping her show off one of her creations.
Forty-one-year-old Gwen looked funky in an animal-print wrap-around tunic and trousers.
By her side, four-year-old Kingston more than held his own on the catwalk, strutting his stuff – while holding mum's hand.
He seems to be following in his mum's fashion footsteps, looking cool in a pair of army pants with tartan sections and a studded belt.
Watching from the audience meanwhile, was Kingston's little brother, two-year-old Zuma.
Gwen's latest collection was divided into six categories. "It's one collection, but like subcategories, which are always my inspiration," she explained.
"We have Ragga girl, we got a soldier girl, we got an English girl, we got a glamour girl, we got a buffalo girl."
Tartan was a key theme in the range, fashioned into suits, jumpers, and loose-fitting trousers.
And the preppy look was very much evident in the form of crisp white shirts paired with Gwen's signature mini-ties.
For something a bit more glam, there were flowing evening gowns in a selection of colours, prints and cuts.
It's a little princess!
