"Amen Jessie! Yes!!!! Women for women all the way. No need for negativity. Let's live in a world where we support each other and raise each other up. Like I said before, positive vibes all the way. Nothing but respect," Jenna wrote, adding a red heart emoji.
The Resident actress captioned her post, "Beautiful message @JessieJ ❤️ #womensupportwomen #respect."
Jenna and Channing have remained on good terms since their split earlier this year. Jenna filed for divorce last month, weeks after ET learned that Channing was dating Jessie. The Magic Mike star has been very "supportive" of his new girlfriend, a source recently told ET.
“Channing wants to do nothing but support Jessie J in every way," the source said. "He has described her as ‘all goodness’ and told his friends she is such ‘a super talent.’ He seems to have become her No. 1 fan. His friends are so happy he has found someone. She is showing the same support to him.”
Jenna, meanwhile, has moved on romantically with actor Steve Kazee. The new couple hasn't been shy when it comes to PDA, and were spotted sharing a kiss during an outing in Beverly Hills on Friday.
Jenna recently told ET that she was "very happy," when asked about the new love in her life. Watch below.
