Pippa Middleton, who became a global sensation as the maid of honor to Kate Middleton at her wedding to Prince William, is set to walk down the aisle herself.

She's engaged to Nico Jackson!

The British event planner's boyfriend, a banker, popped the question during their early December trip to India's Oberoi Amarvilas, insiders share.

Oberoi Amarvilas is a five-star resort, with views of the famed Taj Mahal. "It was exactly how he planned it," one said.

"Very romantic and grand!"

Together for 15 months, the couple were rumored to be engaged back in September. Those rumors were false, but the pair were clearly smitten.

Pip was previously linked by tabloids, at one time or another, to Alex Loudon, Spencer Vegosen, George Percy, James Matthews and even Prince Harry.

But Nico Jackson was clearly The One since they first got together.

Since the engagement, Pippa Middleton, 30, and Nico Jackson, 36, have been keeping a low profile and have been celebrating their news in private.

A source says they plan to spend Boxing Day (December 26) at her family's Bucklebury estate before heading to the Alps for vacation in the new year.

Congratulations to the happy couple and both their families, and here's hoping that Kate Middleton returns the favor as the matron of honor in 2014!
