Demi Moore, 61, shows off her ageless complexion as she joins her on-screen husband Jon Hamm at a photocall for their new series Landman

She is known as one of the best dressed and most beautiful celebrities in Hollywood.

So it’s no surprise that Demi Moore turned heads when she stepped out in style for the Landman photocall in London on Friday.

The actress, 61, stunned in a tan Gucci blazer which she wore over a sheer daisy print shirt, paired with quirky patchwork jeans.

Demi was joined by her on-screen husband Jon Hamm as they posed for snaps together ahead of Landman’s release on Paramount Plus on November 18.

Jon looked dapper in a square printed suit, which he wore over a navy blue jumper.

The series was co-created by the man behind the Yellowstone universe Taylor Sheridan, 53, and podcaster Christian Wallace.

Demi will play the regular role of Cami, whose husband is one of the most powerful oil men in Texas and a friend of Tommy Norris, played by Billy Bob Thornton.

Bruce Willis’ ex-wife was also joined by Thornton who braved the cold in a sleeveless vest, jeans and beanie and Ali Larter who plays Billy’s ex in the series.

Ali wowed in a custom black mini dress with huge shoulder pads and pockets.

The blonde beauty added height to her body with a pair of brown stilettos and styled her long locks in soft curls, which she wore over one shoulder.

Earlier in the day, Demi and Billy Bob Thornton looked ‘terrified’ as they were forced to play Spin To Win on This Morning.

Joined by a very excited Alison Hammond and co-host Dermot O’Leary on the ITV show, the Hollywood legends left fans asking ‘am I tripping?!’

The actors and their Landman co-stars Ali and Jon sat down to discuss the new series, but got more than they bargained for.

After providing insight into the West Texas drama, Billy, 69, admitted he was nervous about coming to the morning show.

The actor explained that he suffers from “terrible anxiety” that often keeps him awake at night, and that he drank champagne on the balcony of his hotel at 6am.

In an attempt to calm his anxiety, Alison pulled him in for a big hug before asking Billy to join in a game of Spin To Win.

Billy spun the wheel for Paula at home, winning her the £1000 jackpot.

The successful caller exclaimed, ‘Oh my god, this is unreal? Thank you so much, you just made all my dreams come true. Great, great.’

During the show, the stars talked about their role in the series Landman, which airs on Paramount+ on November 18.

The series focuses on the massive oil boom in Texas and how some of the biggest moguls in the business will use whatever means necessary to maintain their enormous wealth.

Landman, like Yellowstone, is set in the present and is inspired by the popular podcast Boomtown, which describes an oil boom in west Texas in the 21st century.

The series’ logline describes it as “an up-and-down story of losers and wild billionaires fueling a boom so big it’s reshaping our climate, our economy, and our geopolitics.”
