Natalie Portman dines with Thor: Love and Thunder co-star Tessa Thompson and director Taika Waititi

Natalie Portman and husband Benjamin Millepied walked hand in hand when they arrived at the W hotel in London on Monday evening.

The actress, 41, cut a stylish figure in a black halterneck mini dress with white polka dots and matching loose sleeves.

Thor star Natalie and Benjamin were followed by Tessa Thompson, 38, who co-stars with Tessa in the upcoming movie Thor: Love and Thunder.

Tessa, who plays King Valkyrie in the film, looked glamorous in a short white blouse with large puff sleeves and ruffles.

Her top had black dots and gave a small glimpse of her midriff.

She paired the piece with high-waisted black leggings that ended at the knee.

The star wore a pair of black heels and carried a blue handbag.

Natalie, who portrays Jane Foster, completed her look by wearing a pair of black heels and went for a glamorous look with her makeup, including a bold red lip to brighten up her look.

She was seen smiling walking with her hands clasped together with husband Benjamin, whom she married in 2012.

Benjamin cut a casual figure when he opted for double denim, wearing a blue denim shirt and jeans in a darker shade.

He wore a white T-shirt under his shirt, matching the sneakers he wore on his feet.

Elsewhere, Thor director Taika Waititi stood out in a black shirt with a bold multicolored pattern and matching pants.

The group was out for the upcoming release of Thor: Love and Thunder.

In the fourth Thor film, the hammer-wielding superhero takes on the evil Gorr the God Butcher, played by Christian Bale.

The film is set in the aftermath of Avengers: Endgame, where Thor (Chris Hemsworth) has given up his superhero ways.

He enlists the help of Valkyrie (Tessa Thompson), Jane Foster (Natalie Portman), and other friends to fight Gorr.

Thor: Love and Thunder, directed by Taika Waititi, opens in Australian and UK cinemas on July 7, and in the United States on July 8.
