Pippa Middleton is reportedly engaged to Nico Jackson, but is keeping the news a secret, according to reports. 

Sunday People, a celebrity tabloid reported that Kate Middleton's younger sister is planning to get married to her boyfriend for some months now. The couple is planning a wedding for spring 2014.

As far as Pippa's engagement ring, she is reportedly designing the jewel herself. 

Sources also claim that the springtime wedding is likely to take place at her parents' Bucklebury home, with the ceremony held at the church nearby the estate.

Pippa is currently a writer for a British supermarket magazine, a party-planning book author and a columnist for Vanity Fair. Previously, she worked at her parents' online party-supplies empire.

Pippa and Jackson have been spotted together on several occasions, where they were seen skiing, clubbing and enjoying tennis at Wimbledon. Sunday People noted that Jackson popped the question shortly after the tournament match in July where they watched Andy Murray win his semifinals match.

The couple was most recently spotted walking along Fulham Road in Chelsea in the U.K. during a date night.
