Back in December 2020, Nation made her and Jory's relationship official with a slideshow of snaps of the pair on a camping trip, along with the caption: "Nice to meet you Mr Jory."
On January 11, a source close to Nation revealed that she and Jory were said to be expecting, only a month after their made their romance official, as per Now To Love.
"She's so excited to be having another. She absolutely adores her son Elijah, but has wanted another for a while now," the source revealed.
Continuing, the source said: "Friends all knew something was up when she was seen with either water or a mocktail in hand on New Year's Eve."
Nation, who already has a 10-year-old son Elijah with previous boyfriend Joel Porter, previously made headlines after announcing that she was engaged to girlfriend, and Bachelor In Paradise alum, Maegan Luxa back in 2017.
And while the pair split shortly afterwards, Nation has kept her love life on the down low until now.
