Bachelorette's Jillian & Ed: A Late-Night Piggyback

Reality duo Harris and Swiderski get lovey-dovey at a Chicago nightclub

The Bachelorette love train rolls on.

Reality star Jillian Harris, 30, and her 29-year-old fiancé Ed Swiderski put on a "lovey-dovey" show for pals and guests at Chicago hot spot Enclave nightclub. "They looked smitten throughout the night," an eyewitness tells us. 

The duo's lovefest included lots of PDA...

Between glasses of Dom Perignon and a selection of Grey Goose cocktails, the couple danced closely while sneaking in frequent kisses. 

"Both of them told guests that they're 'committed and very happy,'" says a club source. "They also each said, 'We're so in love.' "

The couple was having so much fun that they didn't leave the club until 2:30 a.m., when Swiderski was seen carrying his ladylove out of the club on his back.
