Actor Rob Lowe has compared the Earl of Dumbarton to the Loch Ness monster.

The West Wing star, who now features in 9-1-1 Lone Star, jokingly made the comparison because he is hardly ever seen in the neighbourhood. 

The Sussexes move to America last March with son Archie after they stepped down as working royals for financial and personal freedom.

But during a rare appearance in his adoptive home town of Montecito, California, Harry was spotted driving his car – and sporting a ponytail – by the Hollywood star.

Lowe described pulling up in his car near the duke during an appearance on The Late Late Show With James Corden, but the chat show host remained sceptical.

The actor told Corden: “I just ran into your countryman, the English treasure Prince Harry, at the stoplight 10 minutes ago.

“He lives about a mile from me. He’s been very reclusive.

“Seeing him in the neighbourhood is like seeing the Loch Ness monster… and I saw him driving his car.

“It looked to me as a casual observer that his hair had grown very long and was pulled back very tightly by what I can only assume was a ponytail.”

Corden was a guest at Harry and Meghan’s wedding and appeared on the couple’s first podcast show in December.

He replied to Lowe: “I’m certain that isn’t true. I think you didn’t see Prince Harry.”

Harry and Meghan bought an £11 million estate in Montecito which is a favourite with celebrities working in nearby Los Angeles.

The actor said he followed the duke back to his home to confirm it was him: “Oh no, it was him because I have to say I followed him to the house to see if the car went in.”
