'Bachelor' contestants hook up; Emily and Jef split?

There's lots of drama in the Bachelor world these days!

First off, former contestants Courtney Robertson and Arie Luyendyk were caught sucking face during what appeared to be a romantic dinner date Thursday night.

This comes just a week after Robertson announced her split from ex-fiance and former Bachelor prize Ben Flajnik. TMZ has photos of Robertson and Luyendyk kissing, caressing and enjoying each other's company in Phoenix. (Luyendyk lives in Scottsdale, Ariz.)

Race car driver Luyendyk, you may remember, vied for the heart of the most recent Bachelorette, southern belle Emily Maynard, who chose bottled water exec Jef Holm over him.

And, speaking of Emily and Jef, several outlets are reporting that the engaged couple may be over.

People reports that Maynard and Holm, who moved to Charlotte, N.C. to be closer to his fiancee and her 7-year-old daughter Ricki, have started spending less time together and may be headed for a break-up.

They've battled numerous tabloid rumors, including claims of cheating and faking their relationship since their engagement aired on ABC this summer, but they have managed to make light of much of the noise via their Twitter accounts.

Last month, Holm rewteeted a follower's joke that poked fun at the numerous rumors about them: "'@MATinney: @EmilyMaynard Next I expect to hear tht Rickis been cheating on both of u with somebody elses parents #giveitarest' haha so good."

Maynard and Holm have yet to comment on the most recent split rumors.
