Katie Holmes is to be a guest judge on 'Project Runway All Stars'.

The actress-and-designer is one of a number of star names who will take up a panellist position on the TV show - a spin-off series based on 'Project Runway' which sees contestants compete with each other to create the best clothes, which are then judged - as well as Kylie Minogue, Stacy Keibler, Liv Tyler and Gretchen Mol.

According to Lifetime, judges Isaac Mizrahi and Georgina Chapman will return, as will mentor Joanna Coles, while Carolyn Murphy will make her debut hosting the programme when the second season premieres on October 25.

Katie and her longtime stylist Jeanne Yang unveiled their new Holmes & Yang collection at New York Fashion Week earlier this month.

The pair opted for a presentation rather than a catwalk show to display their latest creations, which featured camisoles and black leather blazers.

Katie admitted she was ''honoured'' to get the opportunity to showcase their brand's latest line in the US city.

She explained: ''It's an honour to present here. It felt like a very natural step because it's not a whole big fashion show, it's a presentation.

''It reflects the way that we design and the way we've always run our business, which is very quietly and relaxed. So we felt that this was a natural step to have more of an audience and show more buyers.''
