The model siblings were snapped grabbing lunch together at Il Pastaio in Beverly Hills on Wednesday (25 November), as Gigi's love life continues to make headlines.
Gigi was linked to Zayn after the American Music Awards, when they were seen together in a taxi leaving an after party. Of course, two celebrities in a taxi together immediately means romance rumours!
Then, they were pictured together in Los Angeles again two nights later, joining Bella for dinner at celebrity hotspot The Nice Guy.
A source told E! News: "Gigi and Zayn couldn't keep their hands off each other. They were holding hands under the table, whispering in each others' ears, and Zayn [was] holding Gigi's leg. Gigi was so attached to him that she even followed Zayn outside to the patio during a smoke break."
However, another insider told People: "It wasn't a date and there wasn't any PDA. They all had a fun time, but it didn't seem romantic or like a date."
Confused? Us too!
Gigi and Zayn are both single, as Gigi split from Joe Jonas earlier this month, and Zayn ended his engagement to Little Mix's Perrie Edwards in July.
