TomKat are here and they certainly seem happy about it. Smiling for photographers while braving the cold, the A-list couple are in town to promote Tom's latest flick, Valkyrie. Despite sparking concerns about her weight at the film's Berlin premiere, Katie shined at the London debut last night in a black and blue beaded cocktail dress from Escada's pre-fall '09 collection. Reluctant to get her pins out (and why would you in this weather?) she matched her frock with dark tights and a pair of sparkly lace up heels by Givenchy.
