May the best supermodel win! According to a new report, Bella and Gigi Hadid have taken their sibling rivalry from the catwalk to the altar. “Gigi and Bella have always clashed when it comes to their careers — and now they’re battling over relationship milestones,” a source revealed to Heat magazine

In case you live under a ~literal~ rock, Gigi has been dating Zayn Malik on-and-off since 2015. Despite calling it quits for the second time in March, the 23-year-old and her heartthrob beau are back it

Bella, too, is no stranger to rocky romances. The 22-year-old dated The Weeknd (Abel Tesfaye) for a year-and-a-half before splitting up in 2016. The R&B artist then briefly dated Bella’s friend Selena Gomez, before reuniting with the stunning Victoria’s Secret angel earlier this year.

“[Gigi and Bella] love each other, of course, but they also like to win,” the source continued. “So, now they’re competing to see who can lock things down with their boyfriend first,” they added. 

“Gigi’s talking about eloping with Zayn next year, while Bella’s got her heart set on a big wedding with loads of celeb guests,” the source confessed. “They would both feel very put out if other managed to walk down the aisle first.”

Question is, how does Yolanda Hadid feel about both her daughters making such a monumental decision? “Bella and Gigi’s mom, Yolanda, has tried to tell them they need to wait, but they don’t seem to want to listen,” the source said. “Gigi has always said she wanted to marry Zayn, and she believes that marriage would be really good for him. She thinks it could help him with his issues and give him some stability,” they continued. 

“Bella also thinks that if she and Abel were married, he would change his partying lifestyle and their relationship would stand a better chance of survival. Both of them are acting like they’ve got something to prove, and nothing anyone says is going to stop them,” the source concluded.
