Former “Beverly Hills 90210” resident Jason Priestley, 30, and his wife of only nine months, makeup artist Ashlee Peterson, age undisclosed, have agreed to a trial marital separation, reports USA Today. Further details were not provided. Professionally, Priestley has turned to directing of late, having helmed an episode of “The Beat,” Barry Levinson’s midseason replacement show on UPN. Not that he’s completely turned his back on acting. He’s set to appear in a character role in “Eye of the Beholder,” starring Ashley Judd and Ewan McGregor. It’s a January release.
