'Twas the nightie before Christmas! Rosie Huntington-Whiteley smoulders in snaps from her seasonal lingerie campaign

She's been designing and modelling for Marks & Spencer ever since she starred in their 2013 Alice In Wonderland-inspired Christmas commercial.

And Rosie Huntington-Whiteley unveiled some of the latest offerings from her Rosie For Autograph range on Instagram on Monday, showcasing some seasonally-inspired lingerie designs.

The stunning blonde showed off her toned frame in a figure-flattering silk chemise in a cherry-red silk.

Twas the nightie before Christmas: Rosie Huntington-Whiteley smoulders as she shows off her stunning figure in snaps from her seasonal lingerie campaign for M&S

The vintage-inspired nightwear was one of the model's own designs, featuring a strapped top half, adorned with a lacy finish along the chest, as well as a delicate silk tie at the waist.

The 29-year-old let her lightly-curled tresses tumble around her shoulders as she smouldered straight into the lens.

The model and actress followed this up with a shot which she captioned: 'Baby it's cold outside! Stay cosy this festive season in our famous #RosieForAutograph Shimmer Soft dressing gown.'

The image showed her in an equally festive tone of red, this time in the form of a sweeping satin trim robe, which she wore open as she looked demurely down at the floor.

The star looked radiant in the beautifully soft material with its hood and twin pockets, leaving the robe ajar to showcase her honed figure in a silk and French lace black lingerie twin set.

Completing the trio of snaps, Rosie posted a shot of her leaning against an ornate fireplace, again wearing an open satin-trim gown, this time in black.

Underneath she wore another silk and lace lingerie set, this time in black and cream, with a delicate leafy pattern to it.

Speaking to Stellar last month, Rosie said she's excited for her 30th birthday which falls next year.

'Oh I'm excited, I can't wait to turn 30, I feel so grown up! One of the things I see with women who are older than me is how confident they are within their skin, how they've grown and how they have so much experience in life,' she said.

'And I think that becomes truly beautiful.'

Rosie, who is engaged to actor Jason Statham, said as people get older, they 'learn what works' for them, 'cut the bulls**t' and 'really focus on what makes them happy' while being 'strategic' with their time.

The model sees ageing as a 'privilege,' even if it means inevitable changes to her appearance.

'Who looks forward to their boobs sagging and bum going flat?! No one! I hope by that point there will be other things that really matter,' she concluded.
