As well as returning to the small screen to replace Charlie Sheen in Two and a Half Men, Ashton Kutcher also returned to the runway yesterday. No stranger to the modelling world, Ashton hit the catwalk to open the Colcci show at Sao Paulo Fashion Week. Looking rather awkward and a little unsure of himself, he waltzed down the runway with Victoria's Secret Angel, Alessandra Ambrosio, before making a hasty exit. The pair are all ready well acquainted after fronting the Spring/Summer 2011 campaign for Colcci.

What do you think of Ashton's brief runway performance?
