Lily Allen has confirmed she has a new boyfriend.

In a tweet, which has now been deleted, she wrote: "I had hoped I could keep my relationship quiet until I introduced my boyfriend to my children."

According to legal documents obtained by The Sun on Sunday newspaper, Lily - who has two daughters, Ethel, four, and three-year-old Marnie, with Sam - was in bed with Daniel when her stalker Alex Gray broke into her home at 1.30am on October 2, 2015.

The papers say: "In the early hours of Fri 2 Oct 2015, there as a burglary at Ms Cooper's flat.

"At about 1.30am, Ms Cooper was in her bedroom with her friend Lawrence London. Her two children were asleep in their bedroom, and her nanny was in her bedroom."

The documents reveal Daniel - who was born Lawrence London and goes by the stage name MC Meridian Dan - "got out of bed" to confront Gray after he got into the house through an unlocked back door.

They say: "A man came in she did not know - it was the defendant Mr Gray.

"He was shouting loudly at her, saying 'Where's my Dad?'

"When her friend Lawrence London went to intervene, Mr Gray said words to the effect 'You know who I am stop pretending.'

"Ms Cooper assured Mr London that she did not know who he was, and asked him to get the stranger out of her house.

"Mr London got out of bed, and put his hand on the man's shoulder.

"He was still screaming at Ms Cooper, words to the effect 'She's a b***h, her and her kids.'

"Mr London began to usher him out of the bedroom ... and he left.

"Mr London shut the doors and went back to check on Ms Cooper."

Paranoid schizophrenic Gray, who has stalked the 'Smile' hitmaker since 2009, was sectioned this month after being convicted of burglary and stalking.

Lily recently tweeted: "My stalker is mentally ill, the authorities failed him, his illness escalated and no one seemed to notice or care."

Earlier this month, building firm boss Sam was rumoured to have filed for divorce after five years of marriage, citing infidelity as the reason, but Lily has denied this.

She tweeted: "The story is untrue. Sam has not filed for divorce citing infidelity, neither have I. Wherever it came from, it's a lie."
