"It looks like Pete and Kaia are over. It got very overwhelming for Kaia. Pete has a certain M.O. and he’s very intense to his girlfriends. Kaia is only 18 and it’s a lot to deal with."
It comes after news that the pair were "cooling off" as Pete wanted to focus more on his mental health.
A source told E! News that Pete is "taking a break to work on his mental health," as "it became very clear that he had to go and do this and couldn't wait any longer. This is his second time seeking treatment, his first being in 2016."
The couple started to make headlines back in October 2019, after he was spotted leaving her New York City apartment.
They were then spotted grabbing a meal together at Sadelles in SoHo.
Later, Kaia was spotted with a 'P' necklace in November, and E! News confirmed their relationship.
"Kaia and Pete are definitely in a romantic relationship. They have been friends for a while now and run in the same friend circle but became romantic recently," a source said. "They started hanging out alone more often after meeting up in NYC in October. Kaia expressed she loved Pete’s personality. She thinks he is charming and is very intrigued."
Prior to Kaia, Pete was briefly dating Once Upon A Time in Hollywood actress Margaret Qualley, after being engaged to Ariana Grande.
