Aspiring model Marta Bugalska, 24, was left with a three-inch cut to her head and covered in blood after being battered unconscious at Opal Lounge in Edinburgh.
Her 23-year-old attacker Ashley Katsande hit receptionist Ms Bugalska with a glass before striking her twice more on her lip and then again on her head. Katsande had seen her partner with another woman, and later tried to apologise to Ms Bugalska via a friend on Facebook upon realising she attacked the wrong person.
The attacker has now admitted assault but was spared jail at Edinburgh Sheriff Court earlier this month and told to pay her victim £800 in compensation.
Ms Bugalska told The sun reporter Ben Archibald: 'I was standing by the DJ booth and felt a hand on my arm. Then I got hit in the face by a glass and blacked out.
'She hit me twice more on my lip and again on the head. One blow could've taken my eye out. The glass didn't break, or I may have been killed or disfigured. 'She fell to the ground injured and was struck on the forehead and the mouth.'
Paul Dunne, defending, said Katsande did not know her boyfriend would be at the club that night, adding: 'She was confronted with her partner's infidelity.
'He [also] did not know she was going to be there. She went into the pub and witnessed the embrace and was concerned by this. She took great umbrage at this.'
Sheriff Frank Crowe said: 'You do have a previous conviction for assault and this was a very nasty assault where the girl was left disfigured.
'But you do have a good job and you have supportive friends. I am prepared to give you an opportunity.'
Ms Bugalska has now moved from Livingston to London to work on a catwalk career.
