"Jesse Hawthorne, 26, attacked his victim after turning up drunk at his ex's house
He was unhappy that ex Emma Dickinson was in a relationship with Ashley Cook
Defence barrister blamed an 'inappropriate amount of testosterone' for violence
Hawthorne, of Caerphilly, south Wales, was jailed for two years and five months"
The article doesnt say whether Jesse will go to a male or female prison though...
