Peter Andre's son Junior couldn't resist poking fun at his dad as he wished him a happy birthday this week.

The 14-year-old called Pete the "best dad ever" but said he couldn't imagine being 47.

Junior, who the Mysterious Girl singer shares with Katie Price , took to Instagram to share a cute photo of himself posing with an arm around his dad, who he's already taller than.

The duo appeared to be on a walk through the woods as they smiled for the camera in the snap.

Junior captioned the post: "Happy birthday to the best dad to ever step foot on this earth.

He wrote: "As a father you can only ever wish your children love you; and my boy, now almost 15, wrote something that made me very happy. Plse read his post.
