Boris Becker's estranged wife Sharlely Kerssenberg termed the tennis great a 'devil' over the issue of neglecting his son and stopping child support.
In conversation with German tabloid Bild, Kerssenberg said that Boris can be charming and loving when he wants to but he is also extremely hurtful with words.
She also stated that prison didn't make Boris a better person and the tennis great lives in his own world.
3-time Wimbledon champion spent seven months in a single-occupancy cell in Britain's prison last year for bankruptcy offences.
