Forbes just listed Rob and Kristen among the Top-Earning Screen Couples in Hollywood:
Ranking second behind Grint and Watson is reported real-life couple Kristen Stewart and Robert Pattinson, the stars of the Twilight franchise. All of the Twilight films to date have hit theaters in the last five years, earning $2.5 billion at the global box office. While theHarry Potter series is mostly about Potter’s journey, the Twilight franchise is centered on Stewart and Pattinson’s characters, the human Bella and the vampire Edward. In the most recent movie they got married, with disastrous results. They’ll have a chance to boost their earnings even more when the second part of the last book, Breaking Dawn, is released this coming November.
And what does Rob do with all that cash? - he reportedly spends at least part of it in art, with the help of Drew Barrymore's fiancé Will Kopelman:
According to People Kopelman is a top art advisor with "high-profile clients from Robert Pattinson to Death Cab for Cutie’s Ben Gibbard to Silicon Valley billionaires".
US Weekly adds more:
Kopelman has helped pick out and curate the art collections of such stars as Zooey Deschanel, Robert Pattinson and actress Lake Bell. Kopelman helped Twilight hunk Pattinson, 25, pick out the works of young up-and-coming artists for his abode in L.A.
We say that's a great way to spend your cash if you have it ;)
