Marks & Spencer lingerie model Rosie was wearing a diamond engagement ring when the couple walked the red carpet at the 2016 Golden Globes on Sunday evening.
Whilst the pair did not speak about their relationship or reveal any details about prospective marriage at the event, a spokesperson later confirmed the happy news.
The 28-year-old Victoria Secret star has been dating action-hero Jason Statham, who is 20 years her senior, for five years.
It has not been confirmed where the proposal took place, but the couple have just returned from back-to-back holidays - including a romantic trip to Thailand and a skiing break.
The 48-year-old actor first got together with the Devon-born-model in 2010 and has previously credited her with keeping him grounded.
‘Hollywood is superficial...people want to be your friend in the hope they'll become famous. I miss my mates more than anything but I'm lucky, I have a British girlfriend and thanks to her, I always have a little piece of home with me.
‘I think behind every successful man there's a stronger woman that's responsible for almost every good thing we do.'
Despite her flawless looks and talent, Rosie admitted to Self magazine that she feels like before her relationship with Jason she had never had a ‘proper boyfriend'.
In April last year, the celebrity pair bought their first love nest together, a million pound house in Beverly Hills, Los Angeles.
The Burberry model has also started taking on more acting roles in recent years, she starred in Transformers films and Mad Max: Fury Road.
Whilst both Rosie and Jason live their lives in the spotlight, they have been famously private about their relationship.
Although Rosie has confirmed; ‘We are best mates. He makes me laugh every day.'
