The 31-year-old was followed, showered with unwanted gifts and even given a wedding dress by stalker Paul Mason, who told her 'you will be my wife.'
Naming Brooke 'pumpkin,' the dreadlocked 40-year-old would contact the star through fake social media profiles, and even wait at her brother's grave for a chance of seeing her.
At one event he got close enough to give her a hug, and also emailed her: 'your wedding dress is ready.'
Brooke has campaigned tirelessly to combat knife crime after her brother, Ben Kinsella, was killed in 2008.
Indeed stalker Mason attempted to use this as a reason behind his behaviour - saying he was simply supporting the actress's work.
Brooke testified that she felt threatened, frightened and upset by the ordeal.
He was found guilty of stalking and will be sentenced next month.
