's klepto makeup artist was just busted for stealing once again ... this time she allegedly jacked 3 different purses over the course of 6 months -- worth TONS of money!Leslie Lopez
-- who was caught shoplifting twice in Norway back in 2012 -- has been the focus of a police investigation ... over 3 designer handbags from Saks Fifth Avenue in Florida that went missing.
The Bal Harbour PD says Lopez allegedly swooped a Fendi handbag in January worth $2,750 ... then in April she allegedly swooped a Louis Vuitton purse worth the same amount -- and walked out of the store with the purse draped over her shoulder.
Same goes for a Louis Vuitton purse in June worth $3,800 ... only that time she concealed the item inside a shopping bag before walking out.
Leslie turned herself into authorities this week and was charged with 3 counts of grand theft.
Sources close to Leslie tell us she voluntarily went to police because she wanted to set things right by paying for the stolen merch. We're told Leslie has been depressed and on a bunch of meds since her mother's death last year -- but recently she's been cleaning up her act, and as part of that process she surrendered to cops.
