Exclusive NCIS Sneak Peek: Is [Spoiler] A Better Rapper Than LL Cool J's Sam?

Momma said this NCIS sneak peak will knock you out.

This Monday at 9/8c, NCIS: Los Angeles vet LL Cool J brings Special Agent Sam Hanna back to D.C. when he guest-stars on the NCIS mothership.

In Season 22's antepenultimate episode, "After the Storm," when a trio of combat vets are found murdered in a D.C. motel room, the NCIS team tracks down a suspect who refuses to talk to anyone but Sam Hanna.

While Sam is visiting, as revealed to Parker (Gary Cole) in the exclusive clip above, he apparently will make time for a Saturday-night "karaoke date" with Jimmy (Brian Dietzen) and his daughter Victoria.

Wait, Sam Hanna has pipes? Is his speciality by chance rap, akin to that five-time Grammy Awards host? And will Parker be let in on all of this karaoke fun? Press play above for all of those answers!

Leading out of Todd's visit airing April 21, NCIS on April 28 will air "Irreconcilable Differences," in which McGee's (Sean Murray) career and credibility are on the line when he investigates Deputy Director LaRoche (Seamus Dever) for corruption, and Torres (Wilmer Valderrama) and Knight (Katrina Law) receive surprising news.

Then on May 5, in the already-renewed procedural's Season 22 finale, "Nexus," as NCIS investigates a connection between the titular cartel and Parker's longtime nemesis, mob boss Carla Marino (returning guest star Rebecca De Mornay), the team uncovers a high-stakes plot involving stolen nuclear material. "With time running out, Parker is forced into an uneasy alliance that could determine the fate of the operation," the synopsis teases, "and his own future."
