Pippa Middleton appears to be back on with her ex, James Matthews, who she first dated back in 2012.

The younger sister of the Duchess of Cambridge split from her boyfriend of three years, Nico Jackson, back in October.

Matthews’ parents own the Eden Rock hotel in St. Barts, where the rumored new couple spent New Year’s with Middleton's younger brother, James Middleton, and he runs Eden Rock Capital Management.

Last month, Matthews, 40, joined his rumored girlfriend, 32, her brother-in-law Prince William and her mom Carole Middleton for a holiday concert raising money for the Henry van Strabenzee Memorial Fund, People reports.

They both clearly enjoy being active together, as in the past they’ve completed the Otillo race in Sweden together.

These dating rumors put to rest bizarre rumors that surfaced last month that Middleton was dating her brother-in-law, Prince Harry.
