"The relationship with [the woman] was prior to The Bachelor, it simply did not work out," Pavelka toldEntertainment Tonight in a Thursday report.
"There was no overlap with that or any other relationship during the show. It is unfortunate that people such as this are trying to financially capitalize on or disparage my incredible relationship with Vienna. I only wish everyone could be as happy for us as we are happy together."
The woman -- whom RadarOnline has identified as Tanya Douglas from Marianna, FL -- called into the That Guy Kramer radio program on Island 106 in Panama City and alleged that Pavelka contacted her after the finale filmed.
"What I'm saying now has absolutely nothing to do with him and it has gotten so bad and enough people know that we were dating," said Douglas on the radio show, Entertainment Tonight reported.
"He came to my hometown, met my family, met my friends and deceived everyone. And I feel like I'm forced to say something for the sole purpose of defending my honor."
That Guy Kramer host Steve Kramer also said he has confirmed that there was contact between Pavelka and Douglas through pictures and text messages since The Bachelor finished filming, according to Entertainment Tonight.
In addition to Douglas' claim, an unnamed source told RadarOnline earlier this week that Pavelka allegedly tried to convince Douglas that he still loved her and that he left their relationship "on hold" when he left to film The Bachelor because he was only appearing on the show to further an acting career.
