TMZ's pics of Court sucking face with Arie Luyendyk Jr. were taken Thursday at the fancy Quiessence Restaurant in Phoenix. Both are from the area.

They were reportedly "all over each other" the whole time.

Not sure how we feel about them as a couple, but they certainly make an attractive one, and both were single at the time, so good for them ... right?

Arie was the runner-up on The Bachelorette this summer, losing out to Jef Holm, who reportedly parted ways with Emily Maynard within the last week.

He was rumored to The Bachelor in 2013 but lost out to Sean Lowe.

As for Arie's make-out partner, she's newly-single too. Very newly.

Courtney Robertson and Ben Flajnik definitely split earlier this month after getting engaged on The Bachelor earlier this year, saying it just didn't work out.

The Black Widow moves on quickly apparently. No word if she did any #modeling of swimswear or went bikini-less during a late night skinny-dipping sesh.
