The “Circles” singer, 32, attended her friend Carrie Underwood’s concert on Wednesday, September 14, at the Staples Center in Los Angeles.
In the clip, Underwood, 33, is performing her 2005 hit "Before He Cheats” while Kramer sings along. At one point, the actress turns the camera on herself as she lip-synchs the song’s chorus.
Kramer captioned the post, “‘Maybe next time he’ll think before he cheats’. Thanks @carrieunderwood. #music=therapy.”
As Us Weekly previously reported, the One Tree Hill alum split from her husband, 29, last month. According to Entertainment Tonight, Caussin is allegedly being treated at a rehab facility for undisclosed reasons. The former couple welcomed their first child, Jolie Rae, in January.
Kramer is currently competing on season 23 of Dancing With the Stars alongside pro partner Gleb Savchenko. The country star explained on the premiere that she hopes the ABC dancing competition will help her with her breakup.
“I think this show will help me let my guard down,” she said during the Monday, September 12, episode. “My personal life kind of took a hit. I have recently separated from my husband. I really think this process is going to be a huge healing process for me.”
Underwood even sent Kramer flowers after her DWTS debut. “Got the most beautiful flowers last night from my friend @carrieunderwood Thanks girl – love you!!” she captioned a photo of the bouquet.
