Are Gigi Hadid and her younger sister, Bella Hadid, feuding?

As the two sisters prepare to walk the runway in Victoria's Secret's 2016 Fashion Show, a report claims Gigi, who has been known to share her support for Bella on Twitter and Instagram, is clashing with her sister after sharing jobs -- and at odds over their upcoming roles in the VS Fashion Show.

“Like most sisters Gigi and Bella can get competitive, especially since they’re both up for a lot of the same jobs. They don’t usually let it come between them but the Victoria Secret show is a tough one,” an insider told Hollywood Life on Thursday. “Gigi’s on edge about it, she really wants to be the star of the show this year. She’s happy Bella is going to be walking in it too — as long as she doesn’t outshine her.”

Gigi announced weeks ago that she would be returning to the runway for Victoria's Secret for the second year in a row.

“There is no feeling in the world like walking down this runway. I’m elated to say I’ll be returning to the @VictoriasSecret Fashion Show this year,” she captioned an Instagram video of her walking in last year’s show. “Thank you @ed_razek for putting on the show that has been one of my greatest motivators since I was a teenage fan of the Angels, and for making this dream come true for me again.”

Bella also posted a video announcing she would be appearing in the show for the first year in a row.

“I can’t believe it!!!!!!! There’s no better feeling than being confirmed for the @victoriassecret fashion show!! What a dream come true, I feel so appreciative and excited!” she wrote.
