Sienna Millergushed over her younger boyfriend Oli Green and revealed they 'fell in love quickly' as she stunned in a new Harper's Bazaar shoot on Wednesday.
The actress, 42, and Oli, 27, were first linked in February 2022 and welcomed a baby daughter together five months ago.
Making rare comments about her fiercely private relationship, she lauded Oli as being 'wise and well-adjusted' and said his generation of men respect women more.
Sienna famously faced public humiliation in 2005 when her then-boyfriend Jude Law, now 51,confessed to cheating on her with his children's nanny Daisy Wright.
Speaking about Oli she said: 'I didn't expect to take it seriously and then quite quickly, I fell in love. I wasn't like, 'I'm gonna get a younger boyfriend.' It was more, 'F*ck! Why are you young? That's so annoying.'

'There is a difference in the way that generation of men respect women. It's specific to him, he is very wise and well-adjusted, but I do believe it's also that generation.
'They have grown up with a slightly more level playing field. I see it in his female friends as well as in the men.'
As well as the five-month old she shares with Oli, she has daughter Marlowe, 11, with her ex partner Tom Sturridge.
In the candid interview she said having her second child has been a 'cathartic, healing experience'.
The blonde beauty said:'I'm in heaven. It's been a cathartic, healing experience, which sounds woo-woo, but it's grounded in a way that reflects the life that I want to be living.'
For the accompanying photoshoot she stunned in a black and white polka dot playsuit that showed off her toned legs.

It comes after last week Siennagave a very rare insight into motherhood as she discussed her daughter being a young Anna Wintour as she's 'very critical' about her fashion choices.
Sienna opened up about family life during a candid interview with The Guardian, following a 'rough baby night' with her youngest daughter.
She explained that the 10-year age gap between her daughters is, 'actually quite useful because one is tiny and portable, and the other is becoming increasingly independent.'
Speaking about Marlowe, who walked the Cannes red carpet with her mother last month, Sienna said:'She's so stylish and very critical.'
'She's like a young Anna Wintour in her total disdain for some of the things I wear. In New York she thought I was mortifying. She wished I would brush my hair.'
It came as Sienna revealed she has helped design a 33-piece summer capsule collection with Marks & Spencer's.
On the collaboration, Sienna said: 'I have always had a genuine love for M&S - it's a brand that is part of the fabric of British life and holds special associations for so many people.
'Seeing the reaction to the Autumn campaign that I fronted, wasphenomenal. To collaborate on a womenswear design project made total sense. I can't wait to see what customers think of the collection.'
Her collection launched at M&S.com and in 30 stores on June 6.
Sienna is thriving in motherhood as she stole the show on the red carpet in Cannes last month.
She was promoting her new movie - Kevin Costner 's western epic, Horizon: An American Saga.

Her co-star summed her up by saying: 'Her outward beauty is undeniable, but she's so skilled as an actress.'
Embracing being a mother again in her early forties, Sienna is undergoing a renaissance with fans and commentators are declaring that the British actress has 'never looked better' despite the demands of work and having a young family.
Brand and Culture Expert Nick Ede told MailOnline that he predicts that Sienna could be about to 'steal the crown to become the UK's biggest Hollywood star'.
He said: 'Sienna's been looking after herself and got herself red carpet ready knowing this is going to be her big return to the big screen and knowing all eyes will be on her. She's done everything right and she commands The Croisette - the beating heart of Cannes.'
