UPDATED, 2:00pm: We were there on the ground floor of Marks & Spencer this afternoon as Rosie greeted her fans and signed their copies of ELLE. Despite it being (another) rainy London afternoon, she very sweetly chatted to everyone in the line, which meant that she spent far longer than the allocated hour engaging with the public. It was a bit of a family affair - her granny, mum and sister were all there - but that didn't deter the throngs of besuited men who came to catch a glimpse of Rosie's famous curves.

UPDATED, 11:15am: Upstairs, in the M&S press office, we joined an array of fashion press to take a look at her collection. The space had been styled to look like an ultra-feminine vintage bedroom, with lots of roses surrounding pictures of Rosie in the campaign images. She told us that the collection had been inspired by the Thirties, her favourite decade. And that it was a 'collection made for every woman - bras go up to size G and knickers to a size 20, so they can be worn by everyone.'

8:30am: As far as we’re concerned, it’s a very good morning indeed when it begins with Rosie Huntington-Whiteley. This morning, we joined our September cover star at the Marks & Spencer store at Marble Arch in London for the launch of her Rosie for Autograph collection of lingerie, which goes online and in store today.

The supermodel and actress – and now designer – wore a black belted shift dress with a peplum at the hips by Autograph as she posed in front of a rose-covered wall for the photographers at the press call.

Today she will be introducing press to her inaugural collection for M&S then, from 1:00 – 2:00pm, if you head down to the store, you will have a chance to meet the woman herself as she signs copies of this month’s ELLE and pictures of the new collection – so be sure to grab a copy of the September issue before you drop in.
