'Bachelorette' Jillian and Ed on Cheating Rumors: 'This Is Nonsense'

Aug. 5, 2009 -- "The Bachelorette" Jillian Harris and her fiance, Ed Swiderski, say reports that he was cheating on her during and after the show with two different women are "nonsense," and that they are still engaged and happy together.

"It's actually not true at all," Swiderski said on "Good Morning America" today. "Jillian and I have been the target of being one of the very few successful couples on the show. We're clearly being targeted because we're happy."

"This is nonsense. I feel like I'm in high school," Harris said, calling the allegations "totally inaccurate" and "unfortunate."

Us Weekly magazine reported that Swiderski had two other women in his life back home in Chicago during the taping of "The Bachelorette": 24-year-old Betheny Steffan and 29-year-old Lindsey Johnson.

The magazine obtained messages reportedly from Swiderski, 29, claiming that he was involved with the women not just during the show but even after the engagement.

"I think that these women are very hurt, and that they did love Ed. Iit must be very painful," Harris, 30, said. "That was in the past. Those are past relationships."

Swiderski and Harris said they have been "open and honest" about their previous relationships. "He has been very, very clear with me from the very beginning," Harris said. "Ed is not deceiving me.

"This is the last time I'm talking about this," she added.

The couple said they are "absolutely" still engaged. "We are completely in love," Swiderski said.

Harris and Swiderski told "Good Morning America" last week that they were excited to go public with their relationship and that they plan to get married in Canada in the next year and a half.

'Bachelorette' Bombshell: Swiderski Accused of Cheating

On the finale of "The Bachelorette," Harris professed passionate feelings for three suitors: Kiptyn Locke, the sweet surfer; Swiderski, the workaholic who realized he was missing out on love; and Reid Rosenthal, who said, "I love you" just a little too late and made a surprise return on the finale.

In the end, Harris chose Swiderski. "There is no doubt in my mind that I love you," she told Swiderski tearfully on the finale. "I wanted to tell you for so long."

Swiderski got down on one knee and presented her with a diamond engagement ring. "I want you to be with me forever," he said.

But, back in Chicago, Johnson and Steffan claim that Swiderski's reasons for being on "The Bachelorette" were less than genuine.

Johnson, Swiderski's college sweetheart, said they started dating again in February.

"He reassured me many times that it was two weeks and he was just going to be on TV and it was just all a joke," Johnson told "Good Morning America." "He was going to propose to me by the end of the year. He used to say that we would have the most beautiful kids."

Swiderski's other supposed girlfriend, Steffan, says she began dating him in December.

Ian Drew, a senior editor at Us Weekly, said, "Here he was having these other relationships the whole time and implying to the women that he was dating that he was just doing this show to be on TV."

Both women say that Swiderski continued e-mailing them all throughout the taping of the show. Johnson says she received an e-mail April 12, two weeks into the taping, that read, "I miss you dearly. I love you ... hopefully they'll get me home tomorrow."

Three days later, Swiderski told Harris he was leaving "The Bachelorette" because his boss wanted him back in Chicago. It appeared to be a heartbreaking decision.

"This is one of the hardest things I've ever done," he said on the show.

And yet, according to Johnson, she and Swiderski saw each other the next day, April 16, in Chicago and were photographed at a wedding together the following weekend, April 23.

A week later, Swiderski reportedly told both women he was going to Texas for a business trip, but instead flew back to "The Bachelorette" in Los Angeles, and asked Harris to give him another chance.

"I realize that I made a huge mistake," he told her. "I want another shot."

In the end, Swiderski was the last man standing but Harris did have this to say during the finale: "Ed better not ... disappoint me."

On the "After the Final Rose" special, Harris said that after sending second-place finisher Kiptyn Locke home and rejecting Reid Rosenthal's proposal, she was nervous that Swiderski wouldn't ask her to marry him. But he said he knew earlier in the season during their trip to Spain that he would propose if he made it to the final rose ceremony.

"[My ending] was very, very happy," Harris said. "I thought I was going to pass out" when he proposed.

Locke said, "I don't have any hard feelings."

Harris said, "You never did anything wrong," surprised by how emotional she was seeing him for the first time since the show wrapped up taping.

Rosenthal, who Harris sent home because he didn't express his feelings for her, also appeared on "After the Final Rose" and discussed his surprise return and proposal in the finale.

"I thought she was going to say yes," he said, adding that, "of course," he still loves her. "I'm still upset."

"Was there a part of you that wanted to say yes?" Reid asked Harris. "If I told you how I felt earlier, would it change anything?"

Harris said she was confident she made the right decision, but acknowledged it was difficult to face Reid.

Rosenthal accepted her decision and said "you seem happy."

Harris, who made it to the final three in last season's "Bachelor" with Jason Mesnick, became a fan favorite after her bubbly personality and honest remarks about love and life captured America's heart.

If Harris and Swiderski tie the knot, they would be only the second "Bachelor" or "Bachelorette" couple to make it down the aisle. Trista Rehn, who came in second on the first season of "The Bachelor" and was the original "Bachelorette," married her pick, Ryan Sutter.

Today, they have two children.
