Stars Skeet Ulrich, Regina Hall and Megan Boone are leaving 'Law & Order: Los Angeles.' *Doink doink*

According to Deadline Hollywood, Boone is out of the show completely, but Hall may return for a handful of episodes. Ulrich, the first actor cast on 'LOLA' and one of the two main detectives on the series, is also a casualty of the revamp. The series is currently filming episode 12.

Hall's character, ADA Evelyn Price, worked for Alfred Molina's ADA Morales, while Boone's DDA Lauren Stanton worked under Terrence Howard's Joe Dekker. Ulrich's Detective Rex Winters appeared on 'Law & Order: SVU' in a 2010 episode.

When 'Law & Order: Los Angeles' premieres tonight (10PM ET on NBC), it will be the first time in over 20 years that the mothership show, 'Law & Order,' isn't on the air.

Instead, the familiar "chung-chung" sound will be heard on 'SVU,' 'Criminal Intent' (on USA) and this newest edition.

Set amid the bright lights of Hollywood and the gritty streets of South Central, the show stars Skeet Ulrich, Terrence Howard and Alfred Molina, Rachel Ticotin, Corey Stoll and more as the cops and prosecutors charged with dispensing justice in L.A.

'LOLA' kicks off with a crossover from its sibling, 'SVU,' which premieres tonight at 9PM ET. Mariska Hargitay's Olivia Benson heads to Los Angeles for a case about the "backlog of untested rape kits," she told E! News.
