A production partnership between Lopez and her American Idol pal Ryan Seacrest, the show will air with a two-hour premiere episode, said The Hollywood Reporter.
The show is centred on Harlee Santos (Lopez), a single mom and detective working in Brooklyn, who's suddenly pitted against her own precinct when the FBI catches her doing something illegal.
"We're so excited to have locked in a premiere date and can't wait to show audiences what Jennifer and the rest of this incredible cast delivers in this compelling new drama series.
The network is playing up this conflict in a slightly '80s-looking poster and the tagline: "Between good cop and bad cop, there are... Shades of Blue."
"From a marketing perspective, the Jan. 14 date takes advantage of both solid Sunday Night Football games and strong holiday programming through the first week of January," said Jeff Bader, network president of program planning, strategy and research.
"Also, in one of the most-watched weekends of the year (Jan 9-10), we have the NFL Wild Card game and Golden Globes, both of which make for great promotional opportunities.
