According to The Daily Mail, the rugby player's family have been caught befriending the brunette from Port Macquarie on Facebook, and have also been seen 'interacting' with her Bachelor related posts.
Before making her page private, Nick's sister Bernadette reportedly wished Brittany a happy birthday on a photo of her and Nick sharing a steamy kiss in the pool on their single date.
"The most perfect end to the most perfect day. Midnight swim was the best idea Nick had all day x," the 30-year-old captioned the snap.
Leigh Cummins, though to be the honey badger's brother, also reportedly liked the post.
Of course, Brittany and Bernadette could have become friends after Nick's family appeared on the show (which viewers will see in episode 5), and it doesn't necessarily mean that Brittany has won. Or does it?
Brittany and Nick have bonded since night one, when they figured out they were both born in the same hospital and grew up in Port Macquarie.
"Britt… I was chasing a Britt in preschool," the rugby player told her on the red carpet outside the mansion.
"Actually I think you were the boy I was running from," she replied.
In a recent interview with Nova's Fitzy and Wippa, Nick was asked what type of girl he's into. He responded by saying that he usually goes for blondes, but he has since changed that up.
"In the past, they have actually been sandy blonde… and that's why I've had a big changer," Nick said.
So could Brittany be the future Mrs. Badger?
We will have to continue watching The Bachelor on Wednesday and Thursdays at 7:30pm on TEN to find out.
