"In the gauntlet of Hollywood unions, another marriage is about to get the axe. "Sons of Anarchy" villain Adam Arkin (who also happens to be the son of Oscar-winner Alan Arkin, in case you didn't know) and his wife, Phyllis Lyons, are divorcing after nearly 15 years of matrimony. While they've been married for more than a decade, their split is quite recent. Lyons filed the documents in L.A. Superior Court on Tuesday, August 6, citing the tried-and-true cause of irreconcilable differences. The couple got hitched back in 1998, when Adam was in the middle of his run on the hit TV series, "Chicago Hope," and in 2005, they welcomed their son, Emmett Arthur, now 8. Phyllis is asking for joint physical custody of Emmett. Though details beyond this remain pretty slim, Phyllis made it clear that she wants to block the court from awarding Adam any spousal support. She's also asking that Arkin pay all attorney fees. Not surprisingly, neither Adam nor his rep has made any comments. And while we didn't see this particular split coming, we're also not all that surprised. Playing the happy couple in Tinseltown might be one of the toughest roles around. Arkin also has a daughter from a previous marriage."
