In the picture, Kelli is sitting on a couch with her shirt raised up and her belly on full display.
Mariska used her caption to add a ton of enthusiastic hashtags, some of which included: “#MyViewRightNow”, “BabyGoals”, “WorkFamily”, “SpecialBabyUnit”, and “Can’tStopStaring.”
Kelli, who is already mom to 2-year-old Ludo, debuted her bump back in September on the red carpet of the show’s 20th season premiere.
When the actress, who plays Detective Amanda Rollins, was pregnant the first time it was written into the show which was a huge deal for the series. Her pregnancy became a major plotline when it was revealed Lt. Declan Murphy fathered her character's unborn child.
She told E! News back in September, "I looked up when I first got pregnant what other TV shows did and…I guess on The X-Files, she went away. She got abducted by aliens. So I was like, 'That can't happen on SVU. Can't pitch that idea.'"
