Mercedes young gun Kimi Antonelli locked in another pole position, but it was a different Kim who really turned heads at the Monaco Grand Prix.

Reality TV star Kim Kardashian had the Formula 1 paddock at the most famous race of the season in a buzz when she turned up to support Ferrari’s Lewis Hamilton.

In her first Formula 1 paddock appearance, Kardashian was mobbed by photographers as she arrived with her sister, fellow reality TV star Khloe, at the Monaco street circuit.

The Kardashian sisters were photographed watching the on-track action above the Scuderia Ferrari garage during qualifying, in which Hamilton booked third place on the grid.

Kardashian arrived dressed in blue jeans and a lacy black top and sunglasses.

Kardashian and Hamilton, 41, have been rumoured to have been in a relationship since the start of the year.

The SKIMS founder added fuel to speculation about their union, last week posting pictures of herself and Hamilton cycling together.

Kardashian’s arrival also attracted the interest from the seven-time world champion’s fellow drivers with his former Mercedes’ teammate Georger Russell and his partner, Carmen Montero Mundt, also watching her arrival.

In a video posted on Mercedes’ Instagram account, Russell was asked ‘What’s happening down there?’ as they watch from their view above pit lane.

“We’re watching Lewis’s new girlfriend arrive,” Russell said.

Russell’s partner is then asked, ‘Carmen, who is arriving?’

“I think Kim K is here. Oh, yeah,” she said as the video pans to a close up of the Kardashian sisters arriving.

She is then asked, ‘Is it the same when you arrive on track, Carmen?’

“Not quite,” she said.

Hamilton will start from third on the grid behind championship leader Antonelli and Red Bull ace Max Verstappen.
