Jenna-Louise Coleman is "single" again following her split from Richard Madden

A source said: "They will always be friends and have been through a lot together.

"When they first dated they were both jobbing actors, now they are both global stars."

The news comes just days after Jenna was seen flirting with Britain's Prince Harry at a charity polo match in Coworth Park, London.

However, an insider has claimed the pair were just being friendly.

They told the Daily Mirror newspaper: "They were just two young people on a night out chatting. Jenna was honoured to meet Harry, but the pictures make their chat look a lot more intimate than it was.

"They were at a party and were surrounded by friends. It was not flirty and the whole conversation has been blown out of proportion."

However, a party attendee insists the pair were very "tactile", with the 30-year-old royal even taking the actress somewhere quieter to chat.

The witness said: "From their body language it looked like they were really enjoying each other's company. Harry sneaked outside with Jenna. He took her by the hand and led her away from the crowd in the sponsor's tent.

"They sat alone and talked as things were winding up inside the party. It was a very flirty, very tactile encounter. She was leaning in to him and he had his hand on her knee. They were sitting very close, laughing lots and touching each other."
