Kristin Cavallari is keeping her mouth shut about whether she and Chicago Bears quarterback Jay Cutler are a couple again.

We caught up with the Dancing with the Stars castoff the other day and she told us, “I’m not going to answer that.”

But there’s some evidence that suggests the formerly engaged couple is dating again.

• EXHIBIT A: Jay was in the audience for Kristin’s DWTS performance on October 3
• EXHIBIT B: The former couple was photographed holding hands on October 5
• EXHIBIT C: On November 7, Kristin tweeted, “To the man with the best butt in football, good luck tonight @jaycutler6 We’ll be watching”
• EXHIBIT D: On November 7, Jay tweeted back, “@kristincav Thanks babe.”

Kristin and Jay called off their engagement in July and recently The Hills star told Ryan Seacrest on his radio show, “You know what I’ve learned over the years? It’s best not to discuss your relationship.“

It sounds like she’s sticking to that plan. But, it doesn’t take a detective to surmise that they are giving it another go!
