That’s what friends aren’t for!

As rumors of a romance between Kim Kardashian and F1 driver Lewis Hamilton shift into overdrive, Kanye West is “raging,” a source tells Globe — and accusing his former pal of laying the groundwork for the love connection while she was still married to him.

“There’s not a shred of doubt in Kanye’s mind that Lewis was creeping on Kim back when they used to hang out,” says the source. “He’s calling Lewis a slimy, two-faced rat.”

The trio were photographed at various high-profile events together in 2014 and 2015, but the racecar pro, 41, also got to know the rapper, 48, and the reality star, 45, on a more intimate level when he was invited to their marital home, including for their family Easter party a decade ago.

In 2016, Hamilton praised West to City A.M., calling his “outspoken” and advice-filled friend “electrifying in everything he does.”

According to the source, the Yeezy designer “suspected” the track champ of having ulterior motives with Kardashian in the past, but “Lewis always denied it. And Kim said Kanye was just being insecure. Now he feels vindicated.”

The Sun reported on Monday, February 2, that the Skims founder and her new love interest holed up at Estelle Manor in the English countryside before spending time with one another in London and in Paris.

Their reported outings come five years after she filed for divorce from West.

“Kanye is bitter as hell,” says the source. “He’s hoping it all ends in tears for both Lewis and Kim.”
