Declan Donnelly is 40, so we raided the archives for some snaps of him in his floppy-haired PJ and Duncan days

Hip, hip, hooray, it’s Declan Donnelly‘s birthday! Dec turns 40 today (25 September) and it wouldn’t be a proper celebration if we didn’t dig out some embarrassing shots from his past.

Ant and Dec have been TV partners in crime since they were united on screen in Byker Grove, way back in 1990. Dec was the first of the pair to join in 1989 to play Duncan, and Ant joined a year later as PJ. Everyone knows what came next – their short-lived music career as PJ and Duncan.

In case you need reminding of what that was like, here’s a video of Ant and Dec putting on some baggy tracksuits and reliving PJ and Duncan on Saturday Night Takeaway.

The pair went on to have a massively successful presenting career on the likes of SMTV alongside Cat Deeley (ah, we’re getting all nostalgic), Popstars and I’m A Celebrity…Get Me Out Of Here!, as well as, of course, their own show Saturday Night Takeaway.

Last month, Dec married his girlfriend of two years, Ali Astall, who is also Ant and Dec’s manager. We hope she’s spoiling him on his special day!

Look through our gallery above for our favourite Dec moments – we’re particularly fond of Dec’s curtains in his early press shot with Ant. Enjoy!
