After reports came out that the Duchess of Cambridge's younger sister Pippa Middleton and her stockbroker boyfriend Nico Jackson are already engaged, an insider now says those are just merely rumors. The engagement reportedly happened over the summer but the couple kept it under wraps so as not to steal the spotlight from elder sister Kate and the birth of royal baby Prince George.

Despite the engagement news not being confirmed as yet, details of the engagement and the impending wedding have already circulated. After Jackson supposedly proposed to MIddleton, she is apparently putting her party planning skills to good use on her own wedding ceremony which will reportedly take place next spring.

The venue for the wedding ceremony will most likely be in Buckleberry where the Middletons are based. Middleton is said to be designing the ring herself and is now working on the wedding preparations. "Pippa loved seeing Kate go down the aisle and now it is her turn for a fairytale wedding," said a friend of the future bride. "She couldn't be more sure that Nico is the right man for her."

Before meeting Jackson, Middleton had been linked to England cricket player Alex Loudon from 2010 to 2011 and also briefly dated her university friend George Percy in 2012. Jackson is well-accepted into the Middleton brood, already going on family vacations with them.
