Kristin Cavallari: Back Together With Jay Cutler?

Kristin Cavallari wowed everyone Monday night during her "Dancing With The Stars" performance -- especially a certain someone cheering her on from the crowd.

The reality star's former fiance, Chicago Bears quarterback Jay Cutler, was spotted supporting his ex as she performed a samba with her "DWTS" pro Mark Ballas.

The QB also tweeted his support for Cavallari, writing Monday night, "Get your votes in for KC. Great Samba."

So does this mean that the former flames are heating things up again?

Well, maybe.

Last month, it was rumored that the couple was thinking about getting back together.

"They're not officially back together but they're definitely talking and figuring things out," a source told PEOPLE, adding that they are taking things slow this time around.

Cavallari and Cutler started quietly dating last September and announced their engagement in April.

However, the couple suddenly called off their wedding -- just days before Cavallari's wedding dress photo shoot hit newsstands.
