Kim Kardashian and Lewis Hamilton romance: Power couple only on paper?

Kim Kardashian and Lewis Hamilton have lately been dominating headlines for their outings, sending power-couple vibes.

Yet, a body-language expert says, the spark is only on paper.

"There's not a lot of sexual sizzle coming from the Kardashian/Hamilton body language rituals together in these pics," Judi James explains to The Mirror, suggesting the romance lacks chemistry.

"Although Kim's 'secretive' smile and her flattering eye attention on Lewis as they sit in their car do suggest a repeat of some of the stroking flirtatious rituals she was using on him at their last appearance."

She continues, "With her hand hooked into the crook of Lewis's arm, here Kim performs a demure smile as though wanting to look like she's on a first date."

James, however, praises F1 racer Lewis Hamilton for his what she describes as a "gentlemanly role", stating, "Lewis is clearly in a gentlemanly role here, which might tick some new boxes given Kim's dramatic dating history."

Turning her attention back to Kardashian, the expert says the couple could turn heads if they make a joint red-carpet appearance.

"No visual drama here then, and the pair will clearly make a photogenic plus one for each other if they're hitting the Met Ball red carpet together," she concludes.

James's observation comes after Hamilton and Kardashian were snapped on a date night at Nobu in Malibu.

For the outing, the Skims mogul slipped into a stunning bold pink top and flowing skirt, while her partner – who has been reportedly dating her earlier this year – opted for a gray bomber jacket.
