They have kept tight-lipped about their pregnancy, but Tamsin appeared to confirm she was expecting at the Vanity Fair Oscars after-party in February, as she poked fun at her pregnancy diet with fellow guests. 

The couple are the proud parents of a girl who they welcomed in February 2016 after four years of dating.

Last year, Josh spoke about how much he loves being a parent, as announced on the Live! With Kelly and Michael show last year that it had put 'everything into perspective'.

After admitting that he's been very tired of late, Josh gushed: 'The best moments are when you have those individual moments alone in the middle of the night.'
