LI's Jamie-Lynn Sigler to guest on CBS' 'Magnum P.I.'

She doesn't do much TV anymore and hasn't since the days of "Entourage" and "Ugly Betty," but Jericho native Jamie-Lynn Sigler is about to head back to the small screen for a cameo on Monday's "Magnum P.I."

Neither a review screener nor clip were available, so imaginations will have to fill in the blanks left from this brief CBS episode overview of "Bad Day to be a Hero" (CBS/2, Monday at 9 p.m.): "Thomas Magnum (Jay Hernandez) helps Rick Wright's (Zachary Knighton) crush Toni after her illegal poker game is robbed by a masked man. Toni, played by former 'The Sopranos' star Jamie-Lynn Sigler, was hoping to use the game to raise money for her mob debt."

("Mob debt?" Uh huh.)  

Could debt-saddled card shark Toni — who does sound interesting after all — make a return cameo? "Right now, one episode," said a show spokeswoman, "but it is open for her to come back at some point, which does happen in the Lenkov-universe." Peter Lenkov is executive producer and showrunner for "Magnum," while his "universe" extends to CBS dramas "Hawaii Five-O" and "MacGyver."

Sigler, 37, shot her first movie ("Hunting Season") over the summer since delivering her second child in January; she's married to Manhasset native and former minor league baseball player, Cutter Dykstra. Along with "Hunting Season," she'll star in mob movie "Apalachin," which is also scheduled for a 2019 release. Her last full-time series was 2012's "Guys with Kids," the short-lived NBC sitcom co-created by Jimmy Fallon.
