Rumer Willis pairs red mini-dress with cowboy boots for the LA premiere of her western Trail of Vengeance

Rumer Willis glammed up to attend the Los Angeles premiere of her upcoming western Trail of Vengeance on Thursday.

The 36-year-old nepo-baby of Demi Moore and Bruce Willis got into the spirit of the evening by sporting a brown pair of cowboy boots with a sexy red mini-dress selected by stylist Maeve Reilly.

Rumer wore her long blonde locks down and middle-parted for the film festivities.

Willis kept her make-up minimal aside from a bit of mascara, and she darkened her bushy brows.

The My Divorce Party actress portrays widow Katherine Atherton in Johnny Remo's 1875 Missouri-set flick formerly known as Broken Trail, which has yet to secure distribution.

Rumer was joined at the cinema by the filmmaker as well as co-stars James Landry Hébert and Eric Nelsen, who play the characters Zeke and Frank Cooper in Trail of Vengeance.

Also enjoying the premiere was My Best Friend the Baby Snatcher actress Jennifer Taylor sporting a brown blouse, flared blue jeans, and boots.

The Old Way stunt coordinator Dale Gibson showcased his inscribed belt buckle while wearing a black blazer, matching cowboy hat, and blue jeans.

Missing from Willis' side was her 18-month-old daughter Louetta Isley Thomas Willis.

In August, the Kentucky-born, Idaho-raised millennial confirmed via Instastory that she had ended her two-year relationship with babydaddy Derek Richard Thomas: 'I am single momming it and co-parenting!'

Rumer previously loved and left the likes of Armie Hammer, Ricky Whittle, Jason Blair, Chord Overstreet, Micah Alberti, Rafi Gavron, and Harry Morton.

Willis is also set to play Ashley Pullman in Rohit Karn Batra's indie gun crisis drama The Gun on Second Street alongside Poppy Delevingne and Tom Arnold.

The DWTS 2015 Mirrorball champ is also full-blown influencer regularly sharing paid partnership posts for hotels and brands like Vomo Island Fiji, Away, Prenuvo, Cybex, 1 Hotel Central Park, If You Care, Rhode, and ShopMy.

But Rumer first found fame acting in six of her famous parents' projects - Now and Then (1995), Striptease (1996), The Whole Nine Yards (2000), Hostage (2005), Fox's Empire (2017-18), and Air Strike (2018).
