As several outlets have reported, Jef Holm and his former Bachelorette fiancée Emily Maynard have recently been spending time together again. But that doesn’t mean he’s ready to give up the other lady in his life, 23-year old Katianna Bear. In fact, in the nights leading up to Ashley Hebert and J.P. Rosenbaum’s wedding, Jef spent one night with Emily and the next with Katianna, a source exclusively tells Wetpaint Entertainment. And when Emily found out, she hit the roof.

“Emily was in LA for the wedding and Jef was in town, too — although no one was sure exactly why,” the source, an insider close to Jef, explains. “Two nights before Ashley and J.P.’s wedding, he hooked up with Emily at her hotel.” He didn’t, however, spend the night, instead returning to his own lodging closer to the beach.

“The next morning, he picked Katianna up at the Los Angeles airport,” the source adds.

Emily may have been none the wiser…if only social media hadn’t gotten in the way.

“Jef, Katianna, and Arie [Luyendyk, Jr.] took a day trip to San Diego, where they posted pictures of themselves at the zoo,” the source continues. “Once Emily saw that he was with Katianna – only a day after hooking up with her — she was disgusted.”

“Emily and Jef started fighting over text and it got really vicious. They both have dirt on each other stored in their phones and they weren’t shy about reminding each other about it.”

So what led to the change of heart that caused Jef to fly to Charlotte the weekend of December 17, 2012 — and Emily to agree to see him?

“No one knows,” the source says. “I think Emily is still hung up on him. And I do think he would get back together with her if she agrees. But, like the magazine reports say, is it for the right reasons? Does he really love her… or is he looking to extend his 15 minutes?”
