David's been extremely busy zipping around all over the place today to promote the first episode of Single Father (which starts at 9pm this Sunday on BBC One)
He's been doing radio interviews galore with appearances on Heart Breakfast, The Christian O'Connell Breakfast Show and 5Live.
He's also recorded a chat with Woman's Hour which will air tomorrow at 10am on Radio 4.
Check out some great photos of him from his travels today below:
