Kate's younger sister indulges in a PDA

Pippa Middleton was spotted enjoying a passionate moment with new boyfriend Nico Jackson on a skiing trip last week.

Kate‘s little sister, 29, didn’t care who saw her kiss stockbroker Nico, 35, during their romantic break in Zermatt, Switzerland.

‘Pippa Middleton snogging her boyf aggressively next to me at the bar. Tempted by tabloid fee,’ Tweeted an onlooker.

Chalet firm Mountain Exposure wrote: ‘Pippa Middleton wandering round Zermatt. Let’s hope she’s enjoying the snow!’ 

Before heading off to Switzerland, Pippa and Nico had been holidaying on Caribbean island Mustique, where she introduced him to Kate, brother James and parents Carole and Michael.

Her mum and dad are said to have been ‘charmed’ by the former grammar school pupil.

Nico comes from a totally different background from Pippa‘s other boyfriends. But he can run well with the best of them,’ a friend tells the Daily Mail.

‘He is tall, good-looking and has the most amazing piercing blue eyes. He is incredibly charismatic and stands out from the crowd. He is a really good catch. Everyone is after him.’
