'Robin and I are very excited to share with you all that we're having a baby!' she told her 115k followers. 'The due date us March 1st, Alan's birthday!'

Alan is a reference to Robin's father Alan Thicke, who sadly passed away suddenly from a heart attack in December last year - making the expected date of the baby's arrival particularly poignant. Taking to Instagram to pay tribute at the time, Robin wrote: 'My father passed away today.'

'He was the best man I ever knew. The best friend I ever had. Let's all rejoice and celebrate the joy he brought to every room he was in. We love you Alan Thicke. Thank you for the love. Love, your grateful son.'

Fans couldn't be more delighted for the parents-to-be, with April's post already attracting over 6,000 likes and hundreds of comments.

'I was wondering when you two lovebirds were going to have a baby,' said one excited commenter. 'Yayyyy Congratulations and I wish the best to the both of you guys!'

Another wrote: 'That's why you've been hiding 😂. Congrats to you both @aprillovegeary. Wishing you a smooth and healthy pregnancy'.

'So happy for you two! God is so good and always remember Alan is always watching over you!!,' agreed a third.
