David Tennant's wife Georgia shared a heartfelt post ahead of her eldest son Ty's 18th birthday on Friday, but admitted his plans to celebrate had been dashed by the coronavirus lockdown. Sharing a photo of the budding actor on Instagram, the mum-of-five said he has been "the best thing to ever happen to me" after welcoming him when she was 17.

"In a few short hours this boy will turn 18 and whilst it probably wasn't his dream to spend his birthday stuck in a house with his parents and 4 small siblings, I couldn't be more thrilled I get him all to myself!" Georgia wrote.

"He's been the best thing to ever happen to me and when others doubted the success of our partnership I just knew the day would come when I would get to say… 'I TOLD YOU SO!' And that day is here. Happy Birthday @ty_tenzo. You've made me what I love to be more than anything. Right," she added.

Chatting to The Sun, he said: "Doctor Who is such a massive thing to take on. I don't think I would ever decline the offer. Whoever is truly right for it will get the role. If I am granted that, I will certainly do my best."
