Pippa Middleton's Boyfriend Nico Jackson Find Engagement Rumours 'Embarrassing'

The Duchess of Cambridge's sister, Pippa Middleton and her stockbroker beau Nico Jackson have been dating for just eight months, but that hasn't stopped rumours that the pair are already set to marry from flying about the place.

While Pippa's been taking all the gossip in her stride, poor old Nico is said to be "scared" by the overwhelming pressure to walk down the aisle.

According to reports, NJ doesn't feel "committed enough" to even start thinking out marriage. "That sort of speculation is water off a duck's back to Pippa, who just laughs it off," a source told the Daily Express.

"But it has the opposite effect on Nico - it scares him a bit. He finds it all very embarrassing.

"What's amusing to both of them is that this last 'authoritative' report that they plan to marry in Scotland was simply a tip-off from someone who had seen them getting on a plane to Inverness."

Ah well, we can still speculate, right?
