Ed Swiderski Slept with Lindsey Johnson After He Got Engaged to Jillian Harris, Bethany Steffen Says

The date was June 4.

That's eight full days after Ed Swiderski got down on one knee and popped the question to Jillian Harris on the teary season finale of The Bachelorette.

That was when he railed Lindsey Johnson, according to Us Weekly.

A day later, he sent a flirty text to Bethany Steffen, texting her to "bring beer and condoms" over to his place, Steffen herself tells the gossip magazine.

Smooth line, Ed.

The scorned, humiliated women are speaking out now to warn Jillian Harris about her new fiancee's two-timing ways, which were rumored for months.

"Ed's not worth my time, but if I can help someone avoid heartbreak, I'm gonna do that," Bethany Steffen said of her lying, cheating cad of an ex.

The Bachelorette, Jillian Harris, has apparently been betrayed by fiance Ed Swiderski. In other news, Nick and Vanessa are back on and Jon Gosselin is a "bad dad."

Ed Swiderski was reportedly dating both Steffen and Lindsey Johnson behind each other's backs prior to filming The Bachelorette, which began in late March.

Even while he was on the hit ABC show, he texted Lindsey Johnson that Harris wasn't his "type" and that he prefers "all blondes." He also wrote, "I love you." Cold.

According to the report, Ed lied to Harris when he said he had to bow out of episode five because he thought he'd lose his job as a Chicago software consultant.

Ed eventually returned to the show, and went on to win the final rose. But during his time back home, both Steffen and Johnson say they slept with Swiderski.

He then told them he was off to "a business trip in Texas," when in reality he returned to film episode seven of The Bachelorette and declare to Harris that he had "reprioritized" when it came to balancing work and tight shorts romance.

Reported Ed Swiderski playthings Bethany Steffen and Lindsey Johnson.

Jillian herself has denied the women's claims in an interview, saying "It's not possible ... This is a bump in the road. We are a team and we'll get through it."

But Bethany Steffen warns, "Lindsey and I are both smart girls, and Ed just has this way of making people believe what he wants. Jillian needs to be careful."

Adds Lindsey Johnson, "I feel gross, used and completely violated. It shocks me that he was able to do something like that to me."

Will Jillian Harris and Ed Swiderski last?
