Billionaire media baron Rupert Murdoch is divorcing Jerry Hall after six years of marriage. This will be 91-year-old Murdoch's fourth divorce - and his shortest marriage - however Hall, 65, had not previously been married before tying the knot with the media titan, who is 23 years her senior, in March 2016. Hall previously dated Mick Jagger, with whom she shares four children. They never officially wed during their 22-year relationship. Murdoch is worth $17.7 billion.
