Sienna Miller, 42, dazzles in sheer gown as she brings boyfriend Oli Green, 27, and lookalike daughter Marlowe, 10, to Horizon: An American Saga premiere at Cannes Film Festival

Sienna Miller was supported by her family on Sunday night, as she was joined by her boyfriend and daughter at the premiere of her film Horizon: An American Saga premiere during Cannes Film Festival.

The actress, 42, put on an ethereal display in a semi-sheer gown as she arrived on the red carpet with boyfriend Oli Green, 27, and lookalike daughter Marlowe, 10.

It marks Marlowe’s first ever red carpet appearance, with her famous mother only showing her face for the first time in July 2020 in a spread for Vogue.

Sienna shares Marlowe with her ex Tom Sturridge, who she was in a relationship with from 2011 until 2015.

While the movie star only just recently welcomed a second daughter and first child with Oli, in January.

Sienna held hands with her oldest child as Marlowe and Oli supported her at the premiere of her new epic Western film.

The Anatomy of a Scandal star commanded attention in a flowing lavender gown with ruffles layers. 

The sheer material of the draped dress allowed a glimpse of Sienna’s incredible figure in a plunging playsuit underneath.

Adding a touch of sparkle to the ensemble, the gown boasted a diamond studded neckline. 

Sienna added silver strappy heels to give herself an extra few inches and a bright pink lipstick for a pop of colour.
