A personal trainer who claims to have helped Gwen Stefani get into shape hit a woman so hard that she lost a tooth and was left lying unconscious in a pool of blood, a court has hard. Mike Heatlie, 42, launched the violent attack on Fiona McCartney outside a nightclub in Edinburgh because she did not give him a cigarette. Heatlie, from Edinburgh, was once voted as one of the city's most eligible bachelors and claims to have helped train Stefani before her 2009 U.S tour. At the time, she described him as 'Superman'.

But Ms McCartney is now facing a £7,000 dental bill and says she is too frightened to leave her home after being assaulted by the personal trainer. He pleaded guilty at Edinburgh Sheriff Court in March to the attack. He is due to appear again on April 22 for sentencing. Speaking for the first time about the attack, Ms McCartney, a legal PA from Greenbank in Edinburgh, said: 'I used to love going out on Saturday nights. But since the attack I have been very wary and like to be home by a certain time. 'I don't like to go out to nightclubs now and I get very panicky in crowds after this unprovoked attack. 'I'm on sleeping tablets from a doctor because I don't sleep at all. I still have this constant reminder and feel I can't move on because I still have the injuries from that night. I'm reminded every day of this attack.' Ms McCartney said the incident unfolded after Heatlie approached her while she was with a friend outside The Jam House club in March last year. The Edinburgh-based trainer apparently worked on and off with the No Doubt singer (pictured) since 1997 . A testimony which claims to be from Stefani appears on Heatlie's website, which describes him as 'completely passionate' and a 'wonderful motivator' He asked the pair for a cigarette but neither woman had one to give him. He then lashed out and punched her, she said. Ms McCartney said she still suffers from numbness and aching in her mouth. She is also due to have expensive and painful dental work, over the next few months. Heatlie (pictured above) pleaded guilty at Edinburgh Sheriff Court to the attack . Speaking about the incident, Heatlie said: 'This was an unfortunate incident that occurred last year. 'I have been in touch with Ms McCartney and the situation is now very amicable and both parties, I'm sure, would like to move on from it.' In a text message, which Ms McCartney said had been sent by Heatlie to her partner, the trainer wrote: 'Please pass on my sincerest apologies to your partner Fiona, I wanted to get in touch but obviously couldn't with the case proceedings. 'This incident, that I have virtually no memory of, has turned my life upside down and I can't imagine how it has impacted Fiona's. 'I am so sorry, this is completely out of character for me, I've never been involved in a violent incident in my adult life.' Heatlie used an endorsement from Stefani to help promote his new studio when it opened six years ago. At the time, she described Heatlie as being 'completely passionate about health and fitness'. She said: 'I’m so happy for Mike that he’s opening his own studio. I know it will be a huge success. I can’t wait to start working with him again in preparation for our summer tour. 'Mike is completely passionate about health and fitness and is a wonderful motivator. 'He is tireless, compassionate and makes working out something to look forward to. He is the Superman of my tour.'
