Giselle Shi Jia Wei, 25, pleaded guilty yesterday to an amended charge of attempted culpable homicide not amounting to murder.
She was initially charged with the attempted murder of her ex-girlfriend.
Shi kept dabbing the corners of her eyes with tissue as the amended charge was read out to her.
She had stabbed Ummul Qurratu 'Ain Abdul Rahman, 22, twice in the chest with a knife at a Geylang hotel on July 22, 2012. One of the stabs fractured Miss Ummul's breastbone and punctured the wall of her heart.
Shi and Miss Ummul had a tumultuous relationship which began in July 2011.They broke up about a week before the attack.
After Shi's repeated attempts to reconcile, Miss Ummul agreed to meet her for supper on July 21.
Yesterday, the court heard that before they met, Shi bought a knife with a 10cm-long blade from a supermarket near her home and placed it in her bag.
She had planned to stab both Miss Ummul and herself in a murder-suicide ploy should the reconciliation fail.
Shi's mitigation will be heard next Friday.
For attempted culpable homicide, she faces up to 15 years' jail and a fine.
