The 41-year-old supermodel was spotted enjoying a meal at Notting Hill's Taqueria restaurant with fashion designer friend Stella McCartney, 43, and her children.
Kate looked happy and relaxed despite allegations surrounding her the breakdown of her marriage which have been circulating since July.
With her silver marriage band visible for all to see, the British beauty cut a chic figure in a skintight pair of black jeans which clung to her willowy pins.
The supermodel reportedly split from Jamie Hince two months ago.
Both Kate and The Kills guitarist Jamie have been pictured wearing their wedding rings since the news broke of their alleged split, and neither party have commented on their relationship.
