Their latest joint venture, however, is taking things next level with the sisters veering into what just may be their raciest territory yet with a *very* cheeky photo spread for British Vogue.
Making the best use of their long lean legs and limbs, the handsome 20-somethings shared glimpses of their assets while they strategically covered each other's modesty.
The sister's both posed on the cover of the fashion magazine looking bronzed and handsome however the shot that caught everyone's attention was the provocative photo where the girls are seen naked wrapping their arms around each other.
Accompanying the photoshoot is an interview in which Gigi admits to being protective of Bella, who is only 18 months younger than her. The cover shoots, which features both sisters in extreme close-up, weren't the controversial part.
According to Forbes, based on the earnings of the models from 2016 to 2017 (mostly the 2017 calendar year), Gigi comes in at the fifth spot on the list behind her BFF Kendall Jenner, who earned the No. 1 spot. Accentuating her green eyes with a light dusting of gold eyeshadow, Gigi throws her head back as she smoulders at the camera. "I would do anything for her".
"She's (Bella) one of the only people I'll get aggressive for", said Gigi, adding that she is proud of her and "would do anything for her".
"I post what I think would be normal to post of your boyfriend", said Gigi of her relationship with Zayn Malik.
Although the issue, photographed by Steven Meisel, won't be released on newsstands until February 2, British Vogue has a released an intimate teaser of what to expect inside the pages. "Let's try to not make women into such sexual objects..." they comment.
