Millie Bobby Brown has given fans another glimpse of her enormous engagement ring as she appeared at the opening of Osaka Comic Con in Japan.

The 19-year-old shocked fans last month when she announced she was engaged to Jon Bon Jovi’s son Jake Bongiovi, 20.

Stranger Things star Millie looked sensational in a cropped red co-ord consisting of a studded jacked and hot pants as she greeted fans at the three-day event.

She completed her look – by London-based designer Annie’s Ibiza – with a matching blazer and cowboy boots – but all eyes were fixed on the Eleven actor’s ring finger.

And she put her sparkling ring – which estimated to be worth an eye-watering £120,000 – on show as she formed a heart with her hands while waving to the thousands of fans that had turned out to catch a glimpse of her and a whole host of other stars.

Millie appeared on stage alongside Hannibal star Mads Mikkelsen, 57, with the pair breaking a sake barrel, which symbolises new beginnings and the future to come.

She announced her engagement last month, sharing a stunning image of herself laughing as Jake – who she has been dating since 2021 – threw his arms around her shoulders.

Millie holds on to Jake’s arms, with the ring firmly on show.

She simply captioned the post, which was shared to her 63.4million Instagram followers, ‘I’ve loved you three summers now, honey, I want ’em all 🤍.’

Millie’s future father-in-law Jon Bon Jovi recently broken his silence on the engagement during an interview with Andy Cohen on his SiriusXM show.

The conversation started with Andy saying to Jon: ‘Congratulations, by the way, on the big engagement.’

Confirming his son’s big news, the crooner replied: ‘Mmm, the latest one. Three of my four [kids are now engaged].’

Andy replied: ‘Yes! Three of your four [are] engaged.’ He then said to Jon: ‘You’ve been with Dorothea – she was your high school sweetheart – so you were together when you were young.

‘When your almost-21-year-old says, “I’m getting engaged,” do you worry for them that they’re too young? Do you worry as a dad about how old or how young they are?’

Jon replied: ‘I don’t know if age matters. If you find the right partner and you grow together… my advice really is growing together. [That’s] wise.

‘I think all of my kids have found the people they think they can grow together with and we like ‘em all.’

He continued: ‘Millie’s wonderful. Her whole family are great. Jake is very, very happy.’
