An eyewitness tells HollywoodLife.com Kristin Cavallari supported Jay Cutler at a party for his foundation in Nashville Oct. 28 and apparently, they were all over each other!

After a tumultuous few months, it appears Kristin Cavallari and her boyfriend, Jay Cutler, have officially reignited their spark! We’d heard they were working things out after previously calling off their engagement, but a HollywoodLife.com spy actually saw them kissing and making up last night in Nashville.

“Kristin and Jay are 100% back on,” our insider says. “Kristin came to Nashville to attend the annual Block & White Party at Viargo, which is an event that works with the Jay Cutler Foundation. She was ALL over him all night.”

According to our eyewitness, Kristin, 24, couldn’t get enough of her 28-year-old Chicago Bears quarterback at the party.

“She really wanted to be around him at all costs,” the source says. “She was very much the puppy dog-type girlfriend. Trust me, there was a ton of PDA all night.”

Jay originally broke off the engagement last July, but earlier this month he sat in the Dancing with the Stars audience to support Kristin on the show, igniting reports they were starting to work things out.

Do YOU think they’ll end up getting married this time around?
