Princess Diana's 28-Yr-Old NieceĀ And 60-Yr-Old $100m Fashion Tycoon Go Public With Their RomanceĀ 

They have taken pains to keep a lid on their romance since it was revealed last summer.

But with a subtle hand resting on his shoulder, Lady Kitty Spencer gives the game away at last – in a gesture that publicly confirms her relationship with fashion tycoon Michael Lewis for the first time.

The 28-year-old niece of Princess Diana was spotted in step with her beau – who at 60 is more than twice her age – as they strolled through the streets of Manhattan.
