The big event must have distracted her from her newfound romance with Jay and arguing with Kristin.

The singer infuriated Kristin after going on a date with Jay earlier this month. She’s been hanging out with him ever since and was recently pictured attending a Nashville bar opening with him.

DailyMail.com revealed earlier this month that Kristin had cut all ties with Jana after discovering she had gone on a date with her ex-husband.

The designer of Uncommon James, 34, is furious with her former boyfriend, and an insider tells DailyMail.com exclusively: “Kristin is done with Jana.”

“She feels like it’s a complete stab in the back. Girlfriends don’t do this to each other,” the source added, noting that Kristin immediately “blocked” the singer on social media.

Kramer and Cutler recently enjoyed dinner at Bourbon Steak before “grabbing drinks” at LA Jackson in Nashville, according to People.

“So far it’s only been one date,” the source of their rendezvous noted after fans reported the excursion on @cocktailsandgossip’s Instagram account.

But Cavallari was quick to end her friendship with Kramer, according to the DailyMail.com insider.

“It took her a second after hearing the news that she was seeing Jay to block her on social media.”

Jana and Jay’s date is even more shocking, given the way Kristin supported her ex-boyfriend during her divorce from serial cheater Mike Caussin.

“Nobody knows this, but Kristin recommended Jana to her divorce attorney when she needed help leaving her toxic marriage,” the source reveals.

Meanwhile, it seems that Jana is a pawn in Jay’s plan to win back his ex.

“He’s Not Happy She’s Dating Chase” [Rice] and has been trying to get Kristin back,” an insider told Page six.

That source downplayed Kristin and Jana’s friendship, saying, “Kristin and Jana are just acquaintances and have only met twice. They’re not friends.’
