One source who saw Billie with 28-year-old Mr Ayoub said: 'They spent the whole night chatting and looked very close. They shared a couple of kisses and were holding hands for most of the night.'
Mr Ayoub said yesterday: 'I cannot confirm or deny anything.' Evans and Billie, who is currently working on the new version of Dr Who with Christopher Eccleston, had for years defied the sceptics who never expected their marriage to last after a whirlwind romance.
But they separated in September, with friends saying that Billie had grown tired of the 16-year age gap and all it entails.
Evans had also infuriated her by refusing to visit the Dr Who set in Cardiff, instead insisting that she drive home when she had some rare time off.
Since then he has been seen being 'comforted' by a string of female friends, including Virgin DJ Harriet Scott, but Miss Ayres, who lives in West London, is believed to be his first serious romantic interest since the split.
