Pippa's boyfriend popped the question earlier this month while the two were vacationing at a five-star resort in India, Us Weekly is reporting.
"It was exactly how he planned it," a source tells the site. "Very romantic and grand!"
Nico's mom recently shared her approval for her son's lady love in The Daily Mail, saying that Pippa is "charming."
"We're very pleased," Ulrike Jackson said. "They are happy, and that is all that matters. As long as my children are happy, then I am happy."
Now they have even more reason to celebrate!
The pair have been together for 15 months and have reportedly been celebrating their engagement in private since the proposal.
No word yet on when the wedding will be, but since Pippa works as an event planner, we're sure she's already got some great ideas swirling around!
UPDATE: People magazine has published a report with a source telling them that the engagement rumors are "not true," which contradicts the Us Weekly report. Guess we'll just have to wait and see!
