The former American Idol winner took to Instagram on New Year's Day (01Jan16) and shared a photo of his nearly two-year-old son Oliver playing in a cardbox box, wearing a shirt with the words "Big Brother" on the front.

Allen added the caption, "2016 is gonna be a good year!"

He later told fans during a Twitter question-and-answer session on Saturday (02Jan16) that his wife, Katy, is due to give birth in June (16).

The news comes two years after the parents-to-be were involved in a nasty car crash on New Year's Day, 2013, when Katy was pregnant with Oliver.

The couple married in 2008, a year before Allen won American Idol.
