Kim Kardashian and Lewis Hamilton's relationship levels up

Kim Kardashian and Lewis Hamilton have sparked off buzz that their relationship has taken a new serious stage.

This comes as the American media personality and the British racing driver were spotted shopping home decorations in Los Angeles.

The couple, who were initially romantically associated in February, were seen shopping some expensive flooring and furniture in casual attire. 

The fans were in a frenzy after the trip, which heightened speculations that the couple might be cohabiting.

A source told People earlier this year that "Kim's very into him," adding, "They are both busy with their careers, but see each other as much as possible. It's more than just a casual connection."

In recent weeks, the couple has attended a number of high-profile events, such as the Coachella Valley Music and Arts Festival.

Moreover, they had their eldest daughter, North West, and a few of her siblings with them. 

They were also spotted together at Super Bowl LX in February. Hamilton also published a video on social media of him driving a red Ferrari in Tokyo streets with Kardashian in the passenger seat. 

The 45-year-old Kanye's ex-wife marked that experience with a smile, saying, "That's insane,"

Nobody has publicly substantiated or refuted the relationship status or the rumors of moving-in with neither Kardashian nor Hamilton. 

The couple has been friends over the years when their romance was revealed earlier this year. 

Seven-time Formula One world champion Hamilton and SKIMS founder Kardashian still find time to spend together despite their business demands, sources noted.
