Mariska Hargitay and Christopher Meloni enjoyed a "happy" reunion Thursday ahead of the holidays.
"'Tis the season... ran into this #HAPPY man," she captioned the picture.
The snapshot gives a blurry look of a smiling Hargitay and Meloni. The actor posted a clearer picture on his own account.
"Friends #Seehappy #jingleHells," he wrote.
The series stars Meloni as a hitman who can see a little girl's imaginary friend.
"I'm a disgraced detective who now makes his money as a hitman," he said on Wednesday's episode of "Today. "
Hargitay and Meloni co-starred as Detectives Olivia Benson and Elliot Stabler on "Law & Order: SVU."
Meloni left the police procedural in 2011 after 12 seasons, while Hargitay continues to star on the NBC show.
