Uh, maybe Jay Cutler is just a big Nancy Grace fan?
The Chicago Bears quarterback, 28, was the most-watched audience member on Monday's Dancing With the Stars -- where he was seen grinning and applauding Kristin Cavallari, his ex-fiancee whom he dumped in July.
But reality star Cavallari, 24, was mum on the unexpected reunion after the show. "We're not going to talk about it," her pro partner Mark Ballas told Us Weekly.
The Hills alum wouldn't confirm whether she invited her ex to watch her strut to Beyonce's "Crazy in Love." And of the cameras constantly panning to Cutler?
"Well, I have nothing to do with that," she said. "I don't direct where the camera goes." (After dating for about eight months, Cavallari and Cutler got engaged in April 2011. The football hunk abruptly called off their engagement in late July.)
But Cavallari was happy to chat up her samba routine, which garnered a score of 24. "I feel good!" she said. "I had a stressful week, because everyone was telling me how difficult this dance was, so I went into it knowing that and so I put a lot of pressure on myself -- but I think we did a good job!"
