"They finished the last few days because it was becoming increasingly difficult to maintain relationships with the absence of Liam," said a friend of the musician of 19 years to the tabloid The Mirror.
"He could barely see Danielle in recent months and the band has a world tour next year, then things would only get more difficult."
However, the informant revealed that the atmosphere between the two remain friendly: "They broke up, but Liam hopes that things have ended in a cool way. It was the first real love of his life."
