Reality TV trainwreck Heidi Montag called the cops on her own mother Thursday morning, RadarOnline.com has confirmed.
Apparently, Heidi was ticked off when her mom, Darlene Egelhoff, showed up unannounced at the home she shares with husband Spencer Pratt in the Pacific Palisades area near L.A. around 10am PST.
One cop car arrived at the scene, and a source tells us there was no physical altercation between Heidi and her mom.
No arrests were made.
The bad blood between mother and daughter stems from a recent episode of MTV's The Hills in which Egelhoff told Heidi she did not approve of her multiple plastic surgeries.
