Pippa Middleton and Nico Jackson: Couple's Relationship in Trouble due to Long Distance?

Pippa Middleton and her boyfriend Nico Jackson are reportedly having trouble with their long distance relationship.

According to Grazia, the 31-year-old younger sister of Kate Middleton and millionaire stockbroker Jackson are having a hard time after he moved to Geneva, Switzerland for work.

"Long distance has been tough on them," an insider said. "It's difficult to find time for one another and Nico seems to be getting fed up with it all."

The couple's relationship first came to light in 2013 after Chi magazine published photographs of Middleton in an orange and pink bikini, holding hands with Jackson.

USA Today reported that earlier this month Middleton was caught pinching Jackson's cheek as the couple managed to spend time together amid their busy schedule.

In other news, Middleton discussed being an aunt to Prince George during American morning programme the Today Show.

"He's amazing, a very dear boy. He's brought a lot of pleasure and fun for all of us, the whole family," she told host Matt Lauer.

However, the royal family was reportedly not happy about the interview.

"They are furious with Pippa," a source told Radar Online. "They wish that she would shut up. It is obvious that she wants to define her identify and step out of her sister's shadow, however she needs to know her place."
