Pippa Middleton has apparently moved in with millionaire James Matthews. Kate Middleton's sister had recently rekindled her romance with the 40-year-old, whose younger brother is Made In Chelsea star, Spencer Matthews.

According to a report in The Sun, Pippa had a "trial run" with James at his £17m ($24.3m) town house in Chelsea. A source is reported to have said: "It's all moved very quickly. They've been friends for a long time, but James has always been keen."

"Pippa spends most of her time at his house and keeps her car, clothes and toothbrush there. They've tested living together and all seems to have gone well," the insider apparently added.

"Pippa and her brother James still have their flat in Chelsea, which their parents bought, as a bolthole. But as she was spending so much time at James's it made sense to keep stuff there," the source continued.

In October, Pippa split from her boyfriend Nico Jackson. The 30-year-old and millionaire stockbroker Jackson parted ways after dating for more than two years.

"The rumour was that Carole never really liked Nico," another source is reported to have said.

"She didn't think his background really befitted the sister-in-law of a future king and he never came on family holidays. James very much gets her seal of approval. He and Pip have a lot in common," the insider added.

Pippa and James who originally dated back in 2012, have been spotted together following her split from Jackson. A source told People: "It was a mutual decision to split but Pippa was very upset when it ended. They wanted different things."
