The reality TV star and comedian decided to go their separate ways earlier this week due to their demanding work schedules, E! News reported.

Sources told the news organisation that the duo still had "a lot of love and respect for each other" but their work commitments had "made it really difficult to maintain a relationship".

Rumours of the couple's romance began back in October, when Kardashian hosted Saturday Night Live and kissed Davidson during a sketch.

A month later, they publicly confirmed their relationship and have appeared together at a number of events, including the Met Gala.

Davidson has recently been working in Australia, filming for a new film called Wizards!, while Kardashian has remained in the US.

The businesswoman was previously married to rapper Kanye West, and they share four children together - North, Psalm, Chicago and Saint.

Sky News has reached out to representatives of Kim Kardashian and Pete Davidson for comment.

Khloe Kardashian 'welcomes second child'

Meanwhile, Khloe Kardashian has reportedly welcomed her second child with ex-boyfriend Tristan Thompson via a surrogate.

The baby boy was conceived in November, with Kardashian's representative at the time saying she was "incredibly grateful to the extraordinary surrogate for such a beautiful blessing".

The pair already share a four-year-old daughter named True.

Thompson and Kardashian officially split earlier this year after it was revealed that the Chicago Bulls star had fathered a child with another woman while they were together.

He initially denied that he was the baby boy's dad but later publicly apologised to Kardashian after a paternity test proved him wrong.

Thompson also made headlines in 2019 after being caught cheating on Kardashian with her sister Kylie Jenner's best friend Jordyn Woods.

It is understood that Kardashian and Thompson are not back together.
