The exes put on a united front to join their five-year-old for a spooky celebration – weeks after it was revealed Channing was dating British singer Jessie J.
Jenna, 37, looked fantastic in a white and blue princess gown that fell to the floor with a long blue cape.
Later she swapped outfits and changed into a figure hugging Poison Ivy inspired costume.
Channing, 38, pulled out all the stops in his blue costume too and the pair looked content as they took their adorable five-year-old daughter out for a night to remember.
The actor thrilled his fans with his costume and posted a video of himself on Instagram.
He channelled Magic Mike in his outfit and showed off some of his incredible street dance moves.
Their family day out came just weeks after his romance with Price Tag singer Jessie J was revealed.
