Kelly, 34, had been in Austin, Texas to cheer on Verstappen as he claimed his 15th win of the season.

As they left the USA, Kelly posted a number of pictures from the trip to Instagram.

She posed in a towel in her hotel room along with several glamorous pictures from the race weekend.

However, it was a snap of herself smiling whilst wrapped in a Verstappen blanket which caught the attention of fans.

One follower commented: “The Max blanket pic is just a bit cute.”

Another added: “THE BLANKET!”

A third fan also wrote: “The blanket. I love it!”

Meanwhile, one more asked: “Where do we buy the blanket omg.”

Kelly’s smiles came after she had watched her boyfriend secure yet another race victory.

She had earlier been caught on camera looking unimpressed, though, as Verstappen was awarded his trophy.

The model looked nonplussed in the crowd at the Circuit of the Americas as fans cheered on the Dutchman.

Verstappen, 26, has won all but three of the 18 races so far this season and wrapped up the Drivers’ Championship in the Qatar Grand Prix sprint race earlier this month.

He and Kelly first started dating in late 2020, with Kelly having a strong connection to F1.

Her dad Nelson Piquet is a legend of the sport, while her brother Nelson Jr. also raced for Renault.
