Harry Styles and Zoe Kravitz's romance has reportedly left the former One Direction star pals worried.

Recently, Styles and Kravitz sparked engagement rumours less than a year after they were first romantically linked in August 2025.

Now, while friends of the singer adore the actress, insiders claim that some are concerned that Styles is moving too fast.

An insider told Radar Online, "No one in Harry's life is anti-Zoë."

Adding, "In fact, she's very well-liked by all his family and friends, but that doesn't mean people aren't alarmed by how quickly he's proposed. They haven't even been together a year, so it's hard to understand what the rush is."

"Harry tends to burn very hot and then move on quickly so the fear is that he's going to find himself in over his head once the honeymoon stage wears off," the source said.

Furthermore, Styles has dated some stunning ladies including Taylor Swift, Kendall Jenner and Camille Rowe since soaring to stardom. Meanwhile, Kravitz was married to Kar Glusman from 2019 to 2020 and began dating Channing Tatum in 2021. She got engaged to Tatum in 2023 and called it off a year later.

Therefore, some people reportedly worry that Styles is under Kravitz's "spell" and "she's influencing his decisions. Anyone who knows her will say she has very clear ideas about how she wants things to be."

"But Harry is much more go with the flow. Pals fear he'll ultimately feel very controlled, which won't work for him long-term. People around Harry have seen this pattern before," the source said.

Noting that the singer will "build his world around someone" and then suddenly have a change of heart.

Friends are said to be concerned that Harry Styles and Zoe Kravitz both are making big decisions in an "intense love bubble."

But, another pal told the outlet what the real concern is. The insider said, "The concern is that Harry hasn't had the chance to take a step back and see how the relationship functions outside that bubble."

"But Harry's not open to advice right now. His friends don't want to come across as unsupportive, so most people are congratulating him and hoping for the best," they added.
