Caroline Flack puts on a leggy display in yellow leather mini skirt and platform sandals as she parties at book launch

She's been busy filming for The X Factor this summer.

And as the ITV show breaks for a couple of weeks, Caroline Flack made the most of some time off on Tuesday by hitting a book launch party in London.

The new X Factor host looked gorgeous in a yellow leather mini skirt as she left Gizzi Erskine's bash at Prawnography restaurant in East London, which celebrated her new book Gizzi's Healthy Appetite: Food To Nourish The Body And Feed The Soul. 

She's spent weeks filming alongside Rita Ora for the new series of The X Factor. 

And Caroline was obviously missing her pal during a break from shooting, as she was spotted checking out Rita's role in new big screen drama Southpaw during a London cinema trip earlier on Tuesday.

The new X Factor presenter looked gorgeous in a denim mini dress as she visited Cineworld West India Quay for a movie afternoon.
