Reality TV starlet Heidi Montag is almost unrecognizable compared to what she looked like before going under the knife -- and her mom is not happy with her multiple-surgery overhaul!
A source tells People magazine that Heidi's mom, Darlene Egelhoff, is "horrified and having a total breakdown."
Montag is on the cover of People magazine's January 25 issue with the headline "Addicted to Plastic Surgery." She underwent 10 procedures at the end of November -- and wants more.
Heidi tells "Extra" her bra size is now a "triple D, F. I like the F. I actually want H for Heidi."
Egelhoff lives in Crested Butte, Colorado, where "The Hills" star grew up. The source says the 23-year-old is planning a trip back home... and that Egelhoff "can't wait" to confront her daughter.
