`The Hills` star and her parent appeared to have put their differences behind them after losing contact in 2010 because of disagreements over her husband Spencer Pratt.
The relatives enjoyed a wine tasting at the Demetria Estate in California`s Santa Ynez Valley this week.
The two women also enjoyed a Swedish massage together in a couple`s room in the lead up to her appearance at PURE nightclub in Las Vegas, Nevada on 15.6.12.
On Mother`s Day two years ago Darlene told Us Weekly: "Heidi and I aren`t speaking to each other right now. I`ve been writing to Heidi, trying to reach her, but she`s not responding."
In past she had criticised her plastic surgery-obsessed daughter.
She said on the MTV reality show: "How do I go and say that of course I thought you were more beautiful before? I thought you were younger, I thought you were fresher-looking, I thought you were healthier.
"What`s done is done, so that`s a terrible thing for me to say but, yes, that`s how I feel. I felt that you were much more beautiful before and I hope that some of this will fade away."
Spencer, 28, responded: "She`s not god. She didn`t make Heidi. She`s just a vagina!"
