Duchess Catherine's sister - who has been dating stockbroker Nico Jackson for over two years - reportedly enjoyed lunch with banker Alex Loudon in Fulham, north London, on Tuesday (22.09.15), according to the Daily Mail newspaper.

The pair dated for three years before splitting in 2011.

Just days earlier, the stunning 32 year old was seen arm-in-arm with her boyfriend, Nico, 36, and had a grin on her face as they left Violet Hill Studios, which specialises in workshops such as yoga, meditation and healthy cooking.

Meanwhile, Pippa and Catherine's younger brother James Middleton split from his girlfriend of two years, Donna Air, this week.

The 28-year-old businessman left the former TV presenter "heartbroken" and abruptly ended their relationship after dating for two years, because he didn't believe they could "go the distance" together.

A source close to the couple revealed: "The split happened a couple of weeks ago and it was James' decision. Poor Donna. She's more than a little bit heartbroken.

"But he just didn't think it was going to go the distance."
