The actress has been open about her addiction to drugs and has admitted she first tried cocaine at the age of 14.After winning a part in EastEnders she became a regular on the London club scene and her drug use escalated, and by the age of 21 she was spending £400 a day on cocaine.In 2000 fans were shocked when pictures were published that showed Daniella's eroded nasal septum due to excessive drug use.Danniella checked into rehab and six months later appeared on television show The Priory when she claimed she had not used drugs in months. However, hosts Jamie Theakston and Zoe Ball struggled to get coherent answers from her as she was on drugs at the time despite her claims.She later said: "I said I was clean, but it was obvious I wasn't. I look about 50, and my voice was shaky. I should never have been allowed on. They wanted to laugh at me, rip me apart. I despise that sort of thing, but it did me the world of good because watching it I realised, 'I'm so ill.'"When it came to the crunch I thought, 'Hang on. I don't want to die.'"The star went back to rehab to try and beat her drug habit again and underwent reconstructive surgery on her nose.

A couple of years after joining EastEnders Danniella was starting to look more like a star in 2002. She was a regular on the red carpet and was often pictured on a night out and played up to the part by wearing her hair big, long and curly.

In 2014 Daniella was almost back to blonde as she looked more demure in stylish clothes during a television appearance on Lorraine while she wore her brown hair up in a bun.

In 2016, the star was back to her happy and healthy self as she was still off drugs. She turned people's opinions of her around following a successful stint on Celebrity Big Brother in 2016 and EastEnders bosses even invited her back to reprise her role of Sam Mitchell on EastEnders for a short period.
