Harry Styles is reportedly facing calls to consider getting a prenuptial agreement after he was said to have spent up to $1 million on an engagement ring for Zoë Kravitz.

The singer, 32, was reported to have splashed the huge amount of cash on his 37-year-old actress partner's new bling after apparently proposing to her.

Zoë, known for roles in The Batman and Big Little Lies and as the director of Blink Twice, sparked speculation she and Harry have secretly got engaged after she was spotted in New York City on 27 April wearing what experts say was a massive oval-cut diamond on her wedding finger, which they have estimated may have cost up to $1 million.

Reports have described Harry's reported proposal as "traditional and romantic", with insiders claiming Zoë accepted "immediately".

A source has now told RadarOnline.com: "There is a sense this relationship has moved quickly into serious territory, and with that comes practical conversations - particularly around finances and long-term protection."

Another insider told the outlet: "Those close to Harry are advising caution. When assets and public profiles reach this level, a pre-nup is seen as a sensible step rather than a cynical one."

Harry rose to fame with One Direction before establishing a solo career with albums including Harry's House and acting roles such as Don't Worry Darling and is worth an estimated $304 million.

His fortune dwarfs Zoë's estimated net worth of $15 million.

The pair have been linked since 2024, maintaining a largely private relationship despite frequent sightings in London, Rome and New York.

Insiders also told Radar Harry is "deeply" committed to his actress partner.

One source said: "He is entirely devoted - the kind of devotion where he would do anything to make the relationship work."

Another insider described Zoë as "incredibly happy" and "emotionally invested" in her relationship with Harry.

They added: "She feels supported in a way that is steady and grounding."

Zoë was previously married to Karl Glusman, with the pair separating after two years.

The actress was also engaged to Channing Tatum, before their split in October 2024.

At the time, a source said: "The split is amicable. They realised they're at different stages in life."

Another added: "They hadn't been aligned for some time and ultimately grew apart."
