Doctor Who reportedly copped off with Lady Penelope at a top showbiz do in London.

The BBC's new Doctor, David Tennant, took Sophia Myles, who played Lady Penelope in the Thunderbirds movie, to the opening night of Richard E Grant and Anthony Head's West End show.

But, according to the Mirror, the pair spent more time snogging than they did watching the play, Otherwise Engaged.

They then headed to the aftershow bash at London restaurant Cocoon, where they were "all over each other like a rash".

David, who split from actress Keira Malik last month, flaunted his new love in front of guests, including Chris Evans.

The Mirror's source said: "After chatting to Evans, Tennant began passionately snogging Sophia in a corner.

"Then the pair held hands for the rest of the evening. They were all over each other like a rash and quite clearly didn't care who saw them."
