Gigi Hadid has been trying to get a "perkier" bottom prior to the Victoria's Secret Fashion Show.

The 21-year-old model is set to grace the runway for the lingerie giant next month for the second time in her career, and the catwalk icon has admitted for the "last two weeks" her workouts have been focused on toning her pert posterior prior to the show, which will take place in Paris on December 5.

Speaking about her preparation for the highly-anticipated runway appearance, the blonde beauty said: "A lot of squats and eating my carbs ... My butt is what I'm working on for the last two weeks -- need to get it perkier."

And Gigi thinks it's "insane" she will be walking alongside her younger sibling Bella in her first catwalk show for the fashion house.

She explained: "For us to be able to do it together is insane."

And the style icon is equally excited to share the platform with her close friend and 'Keeping Up With the Kardashians' star Kendall Jenner, because they didn't get to model together during Paris Fashion Week earlier this year and it's been a "while" since the duo last worked with one another.

She said: "I didn't get Kenny [Kendall Jenner] with me during fashion month cause she took some time off, so this will be our first show together in a while."

Meanwhile the fashion muse is set to host the American Music Awards (AMAs) and reportedly has between five and 10 outfit changes set for the music bash, which will take place on November 20, although she will only adorn ensembles she is "really excited" to wear.

She explained: "I'll only put outfits on stage that I'm really excited to wear.

"As long as I'm relaxed it goes well, I try not to get myself worked up."
