Pippa Middleton and Nico Jackson

Pippa Middleton is reportedly house hunting with her boyfriend.

The 30-year-old socialite and columnist - who is the younger sister of Britain's Duchess of Cambridge - has sparked rumours she's got engaged to her boyfriend of 18 months, Nico Jackson, after the pair were seen looking at homes in south London, according to the MailOnline.

Pippa and her stockbroker beau, 35, were spotted looking at a number of properties in the Battersea Park area, where the couple have been seen out jogging together in the past, including a £2.5 million four-bedroom terrace house and a £1.95 million three-bedroom flat.

If the duo do decide to invest in a property in the area they may find themselves mingling with their celebrity neighbours, who would include former Boomtown Rats singer Bob Geldof, Duran Duran star Simon Le Bon and his former supermodel wife Yasmin Le Bon.

Meanwhile, Pippa has been working on her cooking skills, perhaps in anticipation of setting up home with Nico - who is reportedly keen to start a family soon.

The party planner recently took part in a culinary crash-course during a visit to the luxury Leela Palace hotel in Udaipur, western India, where she learnt to cook a variety of dishes including laal maas, a hot lamb curry, flatbreads and saffron rice.
