'Bachelorette' Emily Maynard 'Jealous' of Courtney and Arie Relationship?

"Bachelorette" Emily Maynard is said to be regretting her decision to pick finalist Jef Holm over Arie Luyendyk, Jr. following news that the charity owner is now dating season 16 "Bachelor" winner Courtney Robertson.

The 26-year-old single mom reportedly believes that she made the wrong choice by getting engaged to Holm, who she recently broke up with. Now, a new report claims that she is jealous about Luyendyk's relationship with Robertson, 29.

"When Emily saw that Arie was dating Courtney, she got a little jealous. it kind of rubbed salt into the wounds for her because the relationship she had with Jeff didn't work out and it was a tough decision for her to let Arie go," a source reportedly told RadarOnline.com.

"There was no doubt that the pair had an instant chemistry with one another and she was incredibly attracted to him. But she made the wrong choice and now she's sweating if it will affect her fame," the source explained.

Robertson was photographed kissing Luyendyk, 31, just one week after calling off her engagement to "Bachelor" star Ben Flajnik, and the model recently confirmed that they are indeed dating.

"Yes, I'm dating Arie! We're enjoying our time together," Robertson told Life and Style magazine. "I was miserable with Ben; he treated me so badly."

Maynard has been romantically linked to NASCAR truck racer Jason White, 33, in recent days, although a source claims that she believes that a relationship with Luyendyk would be better publicity-wise.

"Emily knew that being together in a celebrity relationship would keep her relevant – but now she's concerned that people will just forget about her," the source said. "That could be part of the reason she's envious, because Arie is dating a fellow reality TV contestant."
