The two had said they plan to marry in the next year and a half. However, USA Weekly reports that Swiderski was still involved with two other women Chicago while the taping was underway.
One of those ladies, a college sweetheart, said Swiderski told her the TV show was just a joke and he didn't plan to marry Harris. Both women said the bachelor continued to send them loving, flirty emails during the show.
The couple denies the cheating rumors and call them "nonsense."
They say they're engaged, happy and are now a target because they're one of the few successful couples created on the show.
