Their television show may be over, but their love isn’t.

Engaged Bachelor stars Ben Flajnik, 29, and Courtney Robertson, 28, are still going strong four months after the California winemaker put a ring on it during the season finale of the hit reality show.

And the twosome “just couldn’t stop touching,” according to an eyewitness in Malibu over the weekend.

And Celebuzz has the exclusive photos.

How is the reality couple showing their affection?

The lovebirds toasted to the good life Sunday, August 5 at the Kia Beach House in Malibu, where they hosted a wine tasting for their close friends the day after Bachelor producers Cassie Lambert and Peter Scalettar tied the knot.

“They couldn’t keep their hands off each other the entire day,” an eyewitness told Celebuzz of the reality couple.

“They were so relaxed and even snuck in a few kisses for each other. They just couldn’t stop touching.”

The insider also reveals the twosome is “working towards their wedding.”

Although the Santa Monica-based model is still living in Los Angeles, Robertson is sharing an apartment with Flajnik in his hometown of San Francisco.

“They’re spending more time together to get acquainted to the idea living together,” adds the eyewitness.

Clearly prepping to fill both her closets, while sipping wine Robertson even went on a mini shopping spree while fulfilling her hostess duties — picking out shirts and tanks from C&C California and summer shorts from Simply Short USA.
