Eddie Cibrian & Wife Party in Las Vegas

Eddie Cibrian's wife Brandi Glanville is standing by her man.

One month after reports of her husband's alleged affair with LeAnn Rimes, model Glanville, 36, and Cibrian, 35, headed to Las Vegas for some dinner and dancing.

"They seem as happy as ever," a source close to the couple tells PEOPLE. "They were very affectionate."

Last month, Cibrian denied reports that he was cheating on his wife with Rimes, 26, his co-star in the Lifetime TV movie Nora Roberts' Northern Lights. Rimes is married to songwriter Dean Sheremet.

In Vegas for a family getaway with sons Mason, 5, and Jake, 2, Cibrian and Glanville joined six friends for an adults night out Tuesday at Palazzo Las Vegas's Lavo restaurant, where they dined on Italian food and did shots at their table. They kissed as they posed for photos.

After dinner, the couple headed hand-in-hand to Lavo's nightclub where they danced throughout the night.
