Has Courtney Robertson already moved on from Ben Flajnik -- with Emily Maynard's Bachelorette ex Arie Luyendyk, Jr.?

On Thursday, six days after Robertson, 29, and Flajnik, 30, announced the end of their 11-month engagement, the single Bachelor star made out with Luyendyk over dinner in Phoenix, Ariz., as new images obtained by TMZ show.

"Beautiful night... #RedWineImFine" Robertson tweeted that evening, along with a photo of two glasses of wine. reported that the L.A.-based model dined with Bachelorette's Luyendyk, 31, at Quiessence Restaurant, the same eatery Flajnik took her to during their hometown date.

Tweeting that he was "a little surprised" to hear of Robertson's date, Flajnik thinks highly of Luyendyk, who placed third on Maynard's season of The Bachelorette. "[Arie] is a solid dude who has his head on straight," Flajnik -- who visited with the fellow reality star when he was in Sonoma, Calif., for an IndyCar racing event -- tweeted at the time. "I can see why everyone liked him on the show."

As they go their separate ways, neither Robertson nor Flajnik is too broken up about calling off their engagement. "Courtney is fine," a source tells the new issue of Us Weekly of Robertson, whom pals say still communicates with her ex-boyfriend Calvin Clark. Flajnik has options too. "He'll date again soon," a friend says of Flajnik, who famously cheated on his fiancee with three women in one weekend. "He's approached by girls all the time!"
