Millie and Jake met through Instagram before they were photographed out together for the first time as a pair in June 2021.

The son of Jon Bon Jovi popped the question April 2023, after two years of dating, in an elaborate underwater proposal while on holiday.

They officially tied the knot in May 2024, in a ‘very small, family ceremony.’

In October, Millie and Jake exchanged vows for a second time in a lavish Italian ceremony at the Villa Cetinale Roman in Tuscany.

The star’s real age has surprised social media users following her appearance at the SAG Awards on Sunday night – with many thinking she looks older.

Millie, who turned 21 on February 19, stepped out for the coveted ceremony at Guild at Shrine Auditorium and Expo Hall in Los Angeles. 

Joined by Jake for the occasion, she was the epitome of elegance in a peach-colored satin gown that showed off her svelte frame.

Millie wore her newly dyed platinum blonde hair – which has left many convinced she’s landed a role playing Britney Spears – in a sleek bun, with a strand left down to frame her face.

Many social media users were stunned by Millie’s age, however, and observed how she appeared to look decades older.

Taking to X, formerly Twitter, one said: ‘Literally had to double check it was her who turned 21 the other day and not 40.’

‘When did 21 going on 45 looks become fashionable?’ asked another.

The duo laughed it up together 

A third observed: ‘Already looking like 30-year-old.’

‘How come she looks 30+?’ asked a fourth.

The Electric State is centered around Millie’s character Michelle who is an orphaned teenager that traverses the American West with a sweet, but mysterious, robot, and an eccentric drifter in search of her younger brother. 

Millie and Chris are joined on-screen by an impressive ensemble including Ke Huy Quan, Jason Alexander, Woody Norman, Giancarlo Esposito and Stanley Tucci.
