The star of YouTube Red’s hit show Cobra Kai, 40, is expecting her second child with husband Ross Kohn, her rep reveals to PEOPLE exclusively.
“We’re mostly excited and only partially terrified to announce that we’re expecting Baby Kohn: Part Deux,” the mom-to-be tells PEOPLE, joking, “Also, I would like to thank baby Spanx for keeping this bump in check during the filming of Cobra Kai season 2.”
Henggeler — who recently wrapped shooting the second season of the Karate Kid spin-off series — and Kohn also share son Oscar Noah, who turns 2 on Jan. 25.
Henggeler marked her son’s first birthday last year with a hilarious hospital photo, where she had a shocked expression on her face as she held her newborn skin-to-skin from her bed and Kohn looked on.
“TBT to exactly one year ago today. I was just minding my business, eating my third fudgecicle when this kid decided he wanted to party,” she captioned the memorable moment.
“Happy 1st Birthday to my wild boy. You make everything awesome,” Henggeler added.
