John Luke and Mary Kate married in 2015, and Baby John Baby John is the couple's first child together. They announced their pregnancy back in May, sharing an outdoor photo of the parents-to-be happily grinning as John Luke held up a photo of an ultra sound.

"Yep, that's a baby!" he wrote along with a blue heart.

Shortly before John Shepherd's birth, the family celebrated John Luke's 24th birthday, with his wife sharing a snap of John Luke blowing out the candles on his birthday cake, which she confirmed in her caption was a Swiss cake roll cake, which sounds great.
