And on Thursday, Monroe continued her support as she posted a fun Instagram snap of the pair on a girls' night out.
Captioning the picture 'date night' the duo looked glammed up and ready to shake their cares away. Monroe – who was part of the group Pistol Annies along with Lambert and Angaleena Presley – was the subject of Lambert and Shelton's post-divorce tweets last month.
It's been a tough time for Lambert, 31, who last week reportedly told fans at a country music festival in Minnesota: "I wish I've been drinking all day. I deserve it: I just got divorced."

"This is not the future we envisioned. And it is with heavy hearts that we move forward separately," the couple said in a statement.
