HERE’S a first look at the newest additions to “Law & Order”:

Milena Govich, who plays Det.

Nina Cassady, and Alana De La Garza, the new assistant DA, Connie Rubirosa.

Govich plays the first-ever female detective on the show (her boss, the mostly office-bound Lt. Van Buren, played by S. Epatha Merkerson, doesn’t count).

De La Garza is the latest in a long line of knockout ADAs, including Jill Hennessy, Angie Harmon, Elisabeth Rohm and most recently, Annie Parisse.

The show, which is shot entirely in New York and has relied for 15 seasons on city grit and grime for its backdrop, appears to be changing gears this season.

From the looks of the two newest cast members, “L&O” is going to show a little more leg this year.

The actresses were working yesterday in Chelsea – shooting a scene at a parochial school on West 25th Street.

In the episode, an Internet posting of a slashed hooker spurs a slew of 911 calls.

When the cops get to the crime scene, it turns out the victim is actually a housewife.
