Zoe Kravitz flashed her new diamond engagement ring from Harry Styles when she stepped out in New York City on Monday.

The 37-year-old made no effort to hide the impressive rock which was on her wedding finger as she looked at her cell phone while wearing a cap that said Boy Next Door. 

The Daily Mail has learned the piece of jewelry most likely cost the former One Direction bandmate a pretty penny.

'Zoe's ring looks to be a ten-carat oval-shaped diamond set in yellow gold,' Chris from The Diamond Bank in Los Angeles told the Daily Mail. 'It was probably custom-made and costs around $1 million. It is bezel set, which is popular these days.'

This sighting comes just as the Daily Mail has learned new details about the shock proposal.

Kravitz has told friends that she said yes right away to Styles's 'old-fashioned, romantic' proposal because she is 'madly in love with him.' The insider added she appreciates that the rock star 'supports her in a beautiful, kind way.'

PageSix reported last week that the lovebirds are set to tie the knot with a source sharing that Styles 'is completely smitten' with her. 

'He would jump off a cliff for her,' the insider said. Meanwhile, Kravitz is said to be 'on cloud nine.' 

The source added that 'no one in their circle is surprised' about the engagement. 

The pair recently fueled rumors of an engagement after Kravitz was pictured flashing a large diamond ring on her finger last week.

This marks Styles's first engagement. Kravitz was previously married to actor Karl Glusman, 38. The pair wed in 2019 before divorcing in 2021.  

She was also engaged to actor Channing Tatum, 45, but they split in October 2024 after three years together.

The Daily Mail has reached out to representatives for Styles and Kravitz for comment. 

In December last year, Kravitz wore the same ring on her left hand, first sparking speculation that they had taken their relationship to the next level.

In snaps taken on Tuesday, Styles visited Kravitz at her hotel in Hampstead in the capital, and the pair held hands on their coffee date.

Styles and Kravitz were first spotted holding hands last August, then a month later, they were pictured out with her father, Lenny Kravitz, suggesting their relationship was getting serious.

Despite their best attempts to keep the relationship out of the spotlight, the couple have since been observed on a number of date nights from London and Rome to Brooklyn. 

Styles recently said he had to have a 'real, honest conversation' with himself as to where he saw himself in five years after watching three of his closest friends get married.

The singer spoke about the 'loneliness' of fame and how he took a three-year hiatus from music to establish what he really wanted in life.

In an interview on Apple Music's The Zane Lowe Show, Styles revealed he wants to get married and start a family. 

He said: 'I stop everything, then I get to decide what I want to bring back in. Like what are really the things that I want in my life?

'If you're like touring all the time and you're doing this all the time and all these things, there's no space to really choose.

'I think I had a real honest conversation with myself about, okay, in five years, what do I want my life to look like? And then how do I make changes to aim at that? I don't want to be the guy who's on his own but was like, oh, I really did it.

'I want to be fulfilled and I want to be in great relationships with people. I want to have great friendships with people. I want a family. I want these things. It just allowed me to go like, okay, what do I have to do to create space to allow these things to happen? I can't just expect them to just happen to me.'

Styles went on to talk about the importance of building a future with the 'right person'.

'They hold you accountable to the person that they know you want to be. I think accepting flaws and stuff is like, yes, having understanding is wonderful, but you know that I want to be better than that.

'So when you challenge me on something. It's a gift to me, actually,' he said.

After the couple spent the holidays together, including Christmas in his hometown of Cheshire, England, an insider told Page Six that the actress believed the pop superstar was her 'soulmate.' 

The source added that Kravitz, whose mother is actress Lisa Bonet, 'feels different' about Styles than her former partners, including ex-husband Glusman and ex-fiancé Tatum.

Previously, an insider told the outlet that 'Harry wouldn’t have gone public with Zoe if it wasn’t anything.' 

In 2024, Kravitz called off her engagement to Tatum after three years of dating. At the time, a source told People, 'The split is amicable. They realized they're at different stages in life.' Another said they 'haven’t been on the same page and grew apart'.

Meanwhile, Styles was previously linked to Olivia Wilde, 42, from January 2021 until November 2022 after they met on the set of her film Don't Worry Darling. He has also been linked to Taylor Swift, Kendall Jenner and Taylor Russell. 

Two months prior to his romance with Kravitz, Styles made headlines when he was photographed sharing a steamy kiss with producer Ella Kenny at Glastonbury Festival and, just weeks later, appeared in Rome spending time with Belgian-Congolese interior architect and designer Kim Mupangilai.
