Mariska Hargitay and Christopher Meloni teamed up for a special reason Saturday.

Mariska, 59, who gave a Law & Order: SVU fan the thrill of a lifetime when they bumped into each other on the same flight, and Christopher, 62, did their part to honor some real life heroes on International Firefighters Day in New York. 

The two, who have been partners in solving crimes on TV for more than 20 years both share photos of their training with the Leary Firefighter Foundation founded by their friend and former Law & Order: Organized Crime co-star Denis Leary, 65.

'Had the most epic day with @learyfirefighters.

 Thank you denisleary for inviting me to join! It was an honor, the actress wrote.

Mariska also shared a video as she climbed out a window and rappelled down a what looked like a two to three story wooden structure in full gear.
