Sean Lowe is leaving on a jet plane, and we don't know when he'll be back again. But we do know that he's being accompanied by his sexy Dancing With The Stars pro-partner, Peta Murgatroyd! These two have formed a close friendship since Sean made the transition from Bachelor to Flash Dancer, and now it looks like they're going on a cross-country trip.

Sean and Peta were seen boarding a North Caroline-bound flight out of LAX on April 25, and everyone seems shocked that his fiancee, Catherine Guidici, didn't come along for the ride. “It was his dance partner from the show,” a source tells Life & Style. “I couldn’t believe my eyes.”

But last week’s trip to North Cackalacky wasn’t the only road trip for Sean and Peta. The dance couple are also currently both hanging in Detroit together. But don’t freak out about it, Bachelor Nation. Sean and Peta have plenty of work to do now that they're entering the finale chapter of Dancing With The Stars, and Sean says Peta is traveling with him for his appearance so they can rehearse. No biggie!

Then again, alleged "insiders" insist that Catherine has a case of the jellies. “Catherine is jealous” Life & Style's source explains. “She had to compete for Sean’s time and affection on the show, and now she has to do it again with Peta.”

We know Sean and Peta have a great connection (Peta even refers to herself and Sean as "Ken and Barbie"), but please. All you have to do is look at Sean and Catherine's selfies to see how head-over-heels in love they are!
