The big booty trend has apparently caught Gigi Hadid. While many girls would love to have a body like hers, the supermodel reportedly wants a bigger butt and she has even considered to get fat transfer to achieve the goal.

A source tells OK! that the girlfriend of Zayn Malik "looked into this a month ago," but was told that she couldn't undergo the procedure because she's too skinny. The source says, "She's not got any spare fat on her so unless she went down the filler route or, even more drastic, a full implant, she's stuck with her current butt."

"She's the skinniest she's ever been and she was advised to put on some weight before considering something like this," the source adds. The 22-year-old catwalk beauty previously reportedly raised concern among her peers because she lost so much weight.

"She started feeling like she was too fat for the high-fashion world," a source said last April. "Constantly being around rail-thin girls finally got to her," the source claimed, adding that the Victoria's Secret model now "barely nibbles on veggies." Noting that Gigi's living an unhealthy lifestyle, the source said, "But she's clearly taking the dieting a bit far. It's getting scary."
