If you can't hear the phrase 'forgive and forget' without picturing the moment Lauren Conrad laid that stinger on ex-BFF Heidi, you, like us, were a die-hard Hills fan.
Checking in with the rich kids of Hollywood and their endless dramz was part and parcel of growing for us, so when they finally called time on the MTV reality show we didn't know how we'd live without Lauren's pensive stares and Whitney's permanently stunned expression.
Thankfully, it looks like our pining for days gone by will soon come to an end if recent uploads to Instagram are anything to go by, but it looks like people are more concerned by Whitney's health than her foray back into reality TV.
Whitney took to social media yesterday to share a selfie which she captioned: "Shoot day!! Filming something extra special for y'all that will air on August 2nd on MTV #100ThingsAboutTheHills," but it didn't exactly get the reaction she anticipated.
While fans were thrilled by the designer's return to the show which launched her career, many were seriously concerned about her appearance.
"OMG….WHITNEY! WTH? Please eat, you are looking sick," wrote one. "You are so beautiful and it's ok put on a couple pounds despite society's expectations."
Echoing these sentiments, another fan of the star wrote: "Always loved you Whitney, but I have to say it looks like you're getting way too thin. Take good care of yourself."
"As long as you're healthy and you're happy the way you are, then I will say no more. Love ya and have fun with filming," they added.
Many Instagram users insisted the 31-year-old had lost too much weight, with another writing: "Way too skinny beautiful lady….have some milkshake – it's good for you."
Whitney will be back on our screens on August 2nd.
