'Super Sized Salon' star Jamie Lopez dies at 37 after heart complications

Jamie Lopez, the driving force behind Babydoll Beauty Couture and star of "Super Sized Salon" has died... TMZ has learned.

Sources close to Lopez tell us she was hospitalized in Las Vegas and died over the weekend from heart complications. A BBC representative said in a statement: "We announce with great sorrow, the death of the founder and owner of Babydoll Beauty Couture, the legendary Jamie Lopez. We ask you, on behalf of the Babydoll family, to give us time to deal with this huge loss."

Lopez, who at one point weighed 846 pounds, designed her living room while confined to bed - too heavy to get up and see the world. The show tracked her progress, including her 400-pound weight loss and her first entry into the living room.

Babydoll Beauty Couture was founded to serve plus-size women...and 'Super Sized Salon' - which aired earlier this year on WE tv - has showcased both staff and customers from the living room. We're told she was about to start filming Season 2.

Jamie was only 37.

RIP
