But the technobromance first began to bud back in May, when Alphabet's autonomous vehicle development company Waymo partnered with Lyft, which gave Waymo a major boost in its effort to catch up with Uber-its main rival in the self-driving auto wars.
The falling out dates back to a year ago when Kalanick became convinced that Waymo meant to deploy its robotic cars in a rival ride-hailing service.
The ride sharing giant announced on Thursday it has raised $1 billion in a new investment round, led by Alphabet's CapitalG investment fund, pushing the San Francisco-based company's valuation to $11 billion.More news: Cher does ABBA: joins cast of "Mamma Mia!" sequel
Lyft has gained market share in the USA this year as Uber suffered from executive turnover and self-inflicted wounds, including a protest over the company's ties to the Trump administration. Lawee was formerly Google's VP of corporate development. The investment brings Lyft's post-money valuation to $11 billion.
Those obstacles have taken their toll: while Uber has been valued as high as $70 billion, that number could fluctuate pending an investment deal with SoftBank, the Japanese conglomerate that's been eying a major stake in Uber. Waymo, Alphabet's self-driving-car company, has partnered with Lyft on the technology.
Lyft, which runs a distant second to Uber, has pushed expansion this year. A trial to decide the issue has been delayed until early December.More news: Qualcomm declares Snapdragon 636 mobile podium
In 2013, Google invested $258 million in Uber through a different venture capital arm called Google Ventures, which was later rebranded under Alphabet as GV.
Last year, Alphabet executive David Drummond stepped down from the Uber board.
Google's self-driving vehicle spin-off Waymo is suing Uber in federal court, alleging that its former ally recruited some of its top engineers as part of an elaborate scheme to steal its trade secrets.More news: Dentist Talwars to visit Dasna jail every fortnight to check inmates
Outwardly, Google's new cash infusion into Lyft is a strategic investment, but it may also be fueled by spite.
