Pippa Middleton is back on the market as she has ended her relationship with Nico Jackson after three years of dating.

A source has told ET that Kate’s little sister actually split from Jackson about two weeks ago.

The reason for the breakup was likely due to the couple spending too much time apart. Jackson, 37, works for a bank in Switzerland and moved to Geneva over the summer.

"Long-distance didn't work, especially with how busy Pippa was," a source told E! News. "A lot of their problems stemmed from the fact she was always busy working—as was he—and they never had time for one another."

The pair has not been photographed together since September. Middleton, 32, has, however, recently been spotted with exes Alex Loudon and James Matthews.

The Duchess’ sis was seen dining with Loudon at an outdoor eatery and on vacation in the Caribbean with Matthews, who was also her brother James’ teammate for the Otillo race in Sweden.
