Christopher Meloni has his own Law & Order show called Organized which he has been filming this year.
But on Tuesday the actor, 61, was seen guest starring on his old TV show Law & Order: Special Victims Unit with Mariska Hargitay. The actor seems to be filming a cross over episode.
The long-running police procedural program SVU is currently working on its forthcoming 24th season, which will premiere in September.
Doing his thing: Christopher Meloni was spotted with Mariska Hargitay while working on the New York City set of Law & Order: Special Victims Unit on Tuesday afternoon
There will reportedly be a lot of Law & Order crossing over this fall, according to TV LINE, as the original Law & Order, Hargitay's SVU and Meloni's Organized Crime will be airing back to back on the same night.
Law & Order Season 22, Law & Order: SVU Season 24 and Law & Order: Organized Crime Season 3 will all premiere September 22.
Meloni has not been pictured filming a guest starring role on SVU in over a year. He wore a long-sleeve t-shirt and a set of slim-fitting navy blue trousers as he filmed his scenes.
Hargitay, 58, opted for an all-black outfit that included a wide-necked shirt and a matching pair of pants.
The actress also accessorized with a set of tinted sunglasses and several pieces of jewelry.
The performer's hair fell onto her shoulders and gave an element of color to her otherwise monotone outfit.

Meloni began portraying Detective Elliot Stabler during Law & Order: Special Victims' first season, which premiered in 1999.
The performer starred alongside Hargitay, who plays Captain Olivia Benson and has remained with the program for its entire length on the air.
The actor stayed with the fan-favorite show for a total of twelve seasons, and he was nominated for the Primetime Emmy Award for Outstanding Lead Actor in a Drama Series in 2006.
He announced that he would be leaving the program in 2013, with unsuccessful salary negotiations being cited as the reason for his departure.

Stabler was subsequently written off the program and given an off-screen exit.
Meloni went on to make a guest appearance on the show during an episode entitled Return of the Prodigal Sun, which premiered last April.
The actor's return to the program was well-received by fans, and his performance was praised by many critics. And it looks like he will be back on SVU this fall.
The performer has since reprised his role as Stabler in Law & Order: Organized Crime, which premiered last year.

In July crew member Johnny Pizzaro was fatally shot on the set of Meloni's spinoff show Law & Order: Organized Crime.
The New York Police Department identified Johnny Pizarro, 31, as the victim of an apparent execution-style killing on the set of Law & Order: Organized Crime.
Pizarro was in charge of parking enforcement on the set, with the murder taking place around 5:15 AM on Wednesday.
The crew member was in his vehicle in Greenpoint when someone opened his door and shot the victim in his face and neck.
