Are Pippa Middleton and Nico Jackson over?

Kate Middleton's sister was snapped on a lunch date with her ex, Alex Loudon, in Fulham.

The two dated for about three years before breaking up in 2011. Soon after, Pippa Middleton and Nico Jackson started dating.

But there must be nothing more to the photo other than two exes having lunch.

About two weeks ago, People published a photo of Nico Jackson and Pippa Middleton looking very much in love, which should put aside the breakup rumors for now.

"Princess Kate's sister, 32, shared a sweet nuzzle with her boyfriend of more than two years, stockbroker Nico Jackson, on September 18," the report said.

"The pair were seen leaving Violet Hill Studios in London," it added. "[Which is a] healing arts center that offers workshops in yoga, meditation and healthy cooking, among other areas of interest."

It was the first time that Pippa Middleton and Nico Jackson were snapped together in a long time after he went overseas for a job. In April, People reported, the two lovebirds were in Venice for a romantic getaway right before Princess Charlotte's christening on May 2.

Just last June, Life & Style magazine reported that Pippa Middleton and Nico Jackson are already engaged.

"Kate is so happy for Pippa and she loves Nico. They all get along so well!" the source said.

In fact, the Duchess of Cambridge even help picked the engagement ring.

"It will definitely be a stunner," the source said of the engagement ring to be given to 31-year-old Pippa Middleton.

Pippa Middleton and Nico Jackson have been dating for three years now, and the engagement rumors came on the heels of the report that they have broken up after he move on a new job overseas.

Both Pippa Middleton and Nico Jackson have yet to respond to the breakup rumors.
