The 21-year-old fashion model - who is currently dating pop star Zayn Malik - has revealed that the 20-year-old beauty regularly helps herself to her garments despite them having completely different styles.

She shared: "She steals from my closet. That's how she is. I just wouldn't go to her house and take her things."

However, Gigi admits that Bella is better at putting outfits together whereas she just throws an ensemble together.

She told People magazine: "We share clothes, but if you gave Bella and I the same piece we would style it completely different, which is fun.

"She has a lot more energy for making a look every day. I kind of just wake up and wear what I feel like wearing. Bella has a lot more motivation to make it an outfit."

Meanwhile, the brunette beauty has revealed that she hasn't asked Gigi for advice for her upcoming gig at the Victoria's Secret Fashion Show because they don't mix their personal lives with work, but said they plan on having a long chat about it all before the event in December.

She said: "We haven't really talked about it. We like to keep work very separate but I am sure when the time comes and it gets closer to the date, we're gonna sit down and have a whole conversation about it. I just have to go and be the best me I can be." Bella will grace the runway in a skimpy underwear set for the lingerie giant at the upcoming catwalk show, which will take place in Paris, France, for what will be the first time she has modelled for the fashion house.

Bella - who was crowned Model of the Year by GQ magazine earlier this year - is set to walk alongside Stella Maxwell, as well as Adriana Lima, Alessandra Ambrosio, Lily Aldridge, Elsa Hosk, Jasmine Tookes, Josephine Skriver, Lais Ribeiro, Martha Hunt, Romee Strijd, Sara Sampaio and Taylor Hill.
