The pair are currently in Los Angeles as they take a break between work commitments and onlookers say they couldn’t keep their hands off each other.

One told The Sun: “We were surprised to see them being so intimate. They looked very much into each other and had that besotted look in their eyes.”

They are understood to have grown closer after Catherine appeared on Adrian’s former ITV chat show That Sunday Night Show and got together earlier this year after the former Doctor Who actress finished her romance with Take That star Jason Orange.

A friend said: “They’re very happy together and love spending time with each other.”

And although the couple are still living separately, they spend a lot of time at each other’s houses.

Adrian split from his wife and mother of his two children, Jane Garvey in 2009, while Catherine has a nine-year-old daughter with former partner Twig Clark.
