These supermodel siblings are taking over!

Gigi and Bella Hadid worked the runway like true pros at the Chanel cruise show in Paris yesterday, and if her recent Vogue Italia blackface controversy was bothering her, G certainly didn't show it as she strutted her stuff in the name of fashion.

In other news, rumors are flying that the stunner and ex Zayn Malik are back together following a brief split after they were spotted making out in NYC , but it's not as cut and dry as it sounds.

"Zayn really wants to be with [Gigi] and has made it clear. He misses her and can't stand being apart. Gigi's a little bit more hesitant. They broke up because it wasn't working and nothing has really changed. She does love him, but she isn't completely sure this is where she wants to be right now. They are both so busy with their careers and traveling the world. It makes it very difficult to be in a relationship," a source dished to E! News.

"They aren't officially back together but they are talking and hanging out. They both needed the space to clear their heads. Zayn reached out to Gigi after a week and they decided to see each other and see how things go. No love was ever lost between them," the source added.

One couple that IS rock solid? Kristen Stewart and Stella Maxwell! The actress attended the show to watch her Victoria's Secret lady love at work. She must feel proud to have such hot arm candy!
