Princess Diana's niece dating 60-year-old millionaire

Lady Kitty Spencer is one of Princess Diana's most well-known relatives, with looks reminiscent of her late aunt and a burgeoning career in fashion. However, the model is now making waves for a different reason.

The 28-year-old was spotted leaving an exclusive Manhattan hotel with her 60-year-old millionaire 'boyfriend' Michael Lewis, head of high-end fashion brand Whistles.

Their relationship was revealed last August, but the pair aren't keen to be spotted by paparazzi, with Lewis exiting the hotel ahead of Spencer to hail a taxi.

While some have speculated the couple are aware of how awkward their 32-year age gap may look, others insist it's a simple case of Lewis and Spencer wanting to maintain their privacy.

In fact, Spencer lived a mostly private life until last year, known more for her modelling career than her royal connections, but that changed in May 2018 when she attended one of the biggest events of the year.

Arriving at Prince Harry and Meghan Markle's wedding in Windsor, royal fans were blown away by her striking resemblance to her late aunt Diana with her fair hair and blue eyes.

Dressed in an emerald and floral Dolce & Gabbana gown, Lady Kitty’s popularity skyrocketed, with her Instagram follower count jumping from 17,000 to more than half a million in just a few days.

It wasn't just social media that recognised her, either; luxury jewellery brand Bulgari also took notice of her striking looks.

Within a week they had signed Spencer on as an ambassador, kick-starting a career high she has been riding ever since.

Now she's been romantically linked to a man six years older than her own father, talk has been focussed on Spencer’s relationship rather than her modelling work.

But when your boyfriend is worth $149 million, we don't suppose you'd care what anyone else says.
