He looks far too [much] like Justin Bieber.’On December 20, Douglas sent his co-star a ‘screen-grab’ of his i Pod, showing that he was listening to Green Eyes, a romantic song by Coldplay which contains the lyrics: ‘Honey you are a rock upon which I stand.’ Away from Twitter, Douglas began escorting Vanessa to events after filming finished.Indeed, it was Twitter-mad Douglas who encouraged his co-star to join the site in the first place, writing: ‘@nookirby [Vanessa’s user name on the site] is my Great Expectations co-star . He was seen cosying up to her during a Mulberry show at London Fashion Week, and they posed together at the Burberry show the next day.The pair also went to the opening night of the English National Ballet production of The Nutcracker together last month.On December 23, Douglas went on what he described on Twitter as a ‘divine’ day out with Vanessa and their actor friend Freddie Fox – taking a speedboat up the Thames to brunch at The Wolseley.Vanessa affectionately mocked Douglas’s turn of phrase, tweeting: ‘ “Divine” brunch.
