Pippa Middleton engaged?

Socialite Pippa Middleton, sister of Duchess of Cambridge Kate Middleton, is reportedly engaged to her stockbroker boyfriend Nico Jackson.

The couple has only been dating for six months. According to a source, Pippa and Nico were delaying the engagement announcement because "they didn't want to take the shine off Kate Middleton and her baby", reports people.com.

If the grapevine is to be believed, Pippa will walk down the aisle next spring. She is "designing a ring" and also busy preparing for her D-day.

There is also buzz that the springtime nuptials are likely to take place at her parents' Bucklebury home, while the ceremony will be held at the church nearby the estate.
