Barefoot, and clad only in her bra and jeans, the troubled singer emerged from a friend’s house in Bow at 5.45am on Sunday looking distressed and agitated – as her mother-in-law says she taking more drugs than ever.

Onlookers said she appeared disorientated as she wandered around on the pavement for several minutes in the freezing cold before disappearing back inside.

The 24-year-old singer, who cancelled her UK tour last week, has ignored pleas from her family to seek help for her addiction to drugs.

They had hoped that she would return to the Causeway Clinic in Essex, where she has already had two failed attempts to get herself clean.

Instead, she has been ‘resting’ at a friend’s house in East London.

Why she came outside only half dressed in the early hours is unclear. One onlooker said she looked up and down the road as if she was waiting for someone, but no one arrived at the house.

“She came out of the house, walked down the drive and wandered around on the pavement for a bit.

“She looked upset and agitated but there was no obvious reason for her to have come outside. It was weird.”
