The 28-year-old single mother is best known for winning Bachelor Richie Strahan's heart in last season's The Bachelor Australia.
The couple, who have been dating for 10-months, only recently had their relationship questioned when photos emerged of Nation locking lips with football teammate, Meagan Luxa.
The romance was reported to have been a complete shock to her then-boyfriend Richie, who claims he was ‘completely blindsided’ by Alex’s controversial new relationship.
A source close to the couple said that Nation and Luxa had 'found love' with each other.
It appears the star is remaining tightlipped about the whole situation.
