James Middleton, the youngest of the Middleton clan, has been facing pressure from his parents and the royal family to keep his relationship with Donna Air on the down low. With Kate Middleton, excuse me, Catherine, Duchess of Cambridge being his sister, James Middleton has to rein in his social life with a famous British celebrity Donna Air. Could the pressure from his parents and his parents affect his relationship with Donna Air? Is a split imminent?

This week, 27-year-old James Middleton was supposed to attend a V.I.P. party thrown by his girlfriend, Donna Air, but pulled a no-show on the day of. The speculations are that he didn't want his girlfriend to be accused of using her royal connections. But what's confusing is that Donna Air was hosting the party in the honor of the Prince Charles' charity. So why the absence, James?

A spy told Vanity Fair, "Donna had invited James and Pippa, but neither of them came. It was odd because we were told they would be coming."

Is James Middleton caving into the pressure? A source close to the Middleton clan told Vanity Fair that his mother, Carole Middleton keeps Donna Air at arms length. While Pippa's beau, Nico Jackson has been invited over many times, Donna has never been invited on holiday with the family. And they have been dating for a year! Maybe they don't approve that she is almost five years older than James with a ten-year-old daughter. For a modern family, the Middletons are putting on airs and getting super conservative!

Or maybe James and Donna are too busy to fit each other into their schedules. The 27-year-old younger brother of Kate Middleton is a well-received entrepreneur. His Cake Kit Company business won Smarta 100 and Haines Watts Young Entrepreneur awards. The Daily Telegraph reported that James Middleton puts in 14-hour days. Compared to Pippa Middleton's weak attempts to become a writer, he seems really dedicated to his business.

And so is Donna. She has been busy promoting the launch of her own jewelry collection, Little Bird. On top of that, she edits a style diary for magazines and makes regular TV appearances.

Donna and James have tried hard to dispel any split rumors so there's some hope for this business-minded couple.
