Scott Blackwood, 30, was battered, stabbed, stamped on, strangled and tied to a bath before an attempt was made to set him on fire.
Georgina Smith, 22, unleashed the sickening violence on Scott - along with co-accused Allan Nicol, 36, and Thomas Moore, 26 - despite claiming that she loved him.
She was found guilty of culpable homicide. Nicol and Moore were convicted of murdering Scott at Wheatley Road, Saltcoats, in July, 2013. Last month they were jailed for life and ordered to serve at least 20 years each.
