But it looks as if they might need to turn their attentions to their younger daughter Nicky, 24, who appears to be modelling herself on Amy Winehouse judging from her dramatic weightloss which has left her looking bony and worryingly thin.
Thinner: Nicky Hilton, seen here in Los Angeles on Thursday, appears to have loss a dramatic amount of weight, leaving her already slim body and her long legs look extremely bony
Bony: A slender Nicky chose a casual outfit to go shopping in
Paris' less limelight-hogging sister, who is three years younger than her ex-jailbird sister was seen out shoe shopping at the Christian Louboutin store in sunny Los Angeles yesterday.
And while wearing a pair of denim shorts, the fashion designer exhibited a pair of ultra-thin, bony legs that would easily earn her a catwalk ban in Madrid.
Her knobbly knees appeared to extend up to her thigh bone, with barely any muscle or fat to fill out her absent curves. A marked contrast from a similar picture of her taken just seven months ago, when an already slim Nicky appeared healthy and curvy.
Spot the difference: Nicky has lost all her body fat, and some muscle it seems, and looks dramatically thinner compared to the picture of the younger Hilton sister on the right, which was taken in July 2007

But the Hilton family's brushes with the law continue as Barron Hilton, the younger brother of Paris and Nicky Hilton, was arrested on February 12 for driving under the influence.
The 18-year-old was arrested on suspicion of driving under the influence after his blood alcohol was found to be nearly twice the legal limit.
