A Melbourne woman accused of smashing her ex-boyfriend's car through his living room wall in December has been granted bail.

Lauren Williamson, 34, sobbed through a bail hearing in the Melbourne Magistrates Court on Wednesday, when it was revealed she is also accused of rear-ending another former partner's car after a break-up.

Magistrate Johanna Metcalf said the 37 days that Williamson had spent in custody might be motivation for her to abide by bail conditions, including a curfew and ban on driving, after hearing evidence she had breached conditions before.

Senior Constable Bonita Di Giangregorio told the court Williamson had gone to her former partner's house just after midnight on December 17 to pick up some furniture.

The man had become frustrated at her repeated calls and started ignoring them, so when she drove into his street and up his driveway, Williamson is also alleged to have tooted her horn repeatedly.
