The model joined the star ahead of this year’s Grand Prix, and in snaps posted online, she can be seen sporting the heavy chain, which is believed to belong to Lewis.
According to The Sun, Kendall’s mum Kris is hoping the pair can strike up a relationship, and a source tells the paper: “She really wants Kendall to date him. Lewis and Kris have become friendly in recent months and she thinks he's perfect for her daughter.
“Kendall usually goes for bad boys like Chris Brown and Justin Bieber so Lewis could be a good influence on her.
“She really enjoyed being in Monaco with Lewis, who personally invited her. And of course any relationship would be a profile boost for her.”
However, it’s not just Kendall who has been spotted cosying up to Lewis, as her pal Gigi Hadid has also joined them in Monaco.
In snaps from Sunday’s racing, Lewis can be seen getting close to Gigi, and they also spent time together at the amFAR gala in Cannes, earlier in the week.
Lewis split from his longtime on-off girlfriend Nicole Scherzinger just months ago, and the former Pussycat Dolls singer later discussed their split.
“I’m devastated that it didn’t work out. It was the hardest decision we had to make, but we made it together,” she said in February. “I love Lewis and I know he loves me.
“We wish nothing but happiness and the very best for one another. I’m trying to stay strong in my faith right now.”
