That mini "JAG" revival with David James Elliott on "NCIS: Los Angeles"just got even better: Catherine Bell, who played "Mac" Sarah MacKenzie on the '90s, series is joining Elliott in a multi-episode arc.

That's right, Harm and Mac will be back together, just like old times. They'll be helping the NCIS crew thwart terrorists, with Mac tracking down an elusive Russian diplomat. And maybe (just maybe) prepping for a full-blown "JAG" reboot?

The duo will reportedly be in the final two episodes of this season and the opening two episodes of next season.

CBS hasn't yet renewed its "NCIS" franchise, but all three series are expected to return.

"Catherine’s 'Mac' was a strong, smart woman who held her own, and then some, in a male dominated world," said "NCIS: Los Angeles" executive producer/showrunner R. Scott Gemmill, who was a writer-producer on the first four seasons of "JAG."

"Not only is it great to be working together again as friends, but to be able to write for Catherine and have her same character interact with our 'NCIS: Los Angeles' characters now, that’s wonderfully surreal. It feels like everything has come full circle," said Gemmill.

Since leaving JAG, Bell has starred on "Army Wives" and "The Good Witch."
