Don’t start shopping for engagement presents just yet – Pippa Middleton isn’t set to wed boyfriend Nico Jackson, PEOPLE has learned.
Speculation was mounting that Kate’s little sister and her beau had gotten engaged, but a source tells PEOPLE “it is not true.”
The rumors heated up after Middleton, 30, took a trip to India earlier this month with her stockbroker boyfriend, 36, and reports claimed he’d popped the question.
The couple have been dating for a year and were first spotted together on a Middleton family vacation in Mustique in February, and they later hit the ski slopes of St. Moritz in March.
“We re very pleased,” Ulrike Jackson said of the couple earlier this year. “They are happy, and that is all that matters.”
