Just days after the reality TV lovebirds announced that they’d split, Swiderski was partying in his hometown of Chicago and enjoying the city’s hot club scene.

Swiderski has been out club-hopping with buddy David Vargas, a contestant on the third season of The Bachelorette, who also lives in the Windy City.

Former friends call Ed “a player” who was “doing shady stuff during their relationship,” RadarOnline.com exclusively reported on Wednesday.

“He’s acting like a single guy,” an insider exclusively told RadarOnline.com. “He’s already moved on and made a fresh start.”

Jillian has reportedly moved out of their Chicago condo and gone back home to Kelowna, B.C., Canada, leaving room for Ed to turn it into a real Bachelor pad.

“We have just been having a tough time, and I needed to go back home,” Harris told OK! magazine.
