The couple has yet to go public, however, it seems like they could be self-isolating together during the COVID-19 shutdown, which SCREAMS relationship!
You have to be pretty comfortable with someone to be locked away with them for weeks on end.
In photos obtained by Page Six, Nina and Shaun were happily riding bikes together, with Shaun also cradling Nina's puppy!
US Weekly has also reported that the rumoured couple went on a holiday together in South Africa together recently, although, they didn't post ANY of it on social media. RUDE!
Sources did reveal the publication that they were spotted kissing before their bike ride, which yeah, is definitely more than friends!
Nina was dating Grant Mellon previously in 2019, before calling it off in November.
As for Shaun, he was previously dating his long-term girlfriend Sarah Barthel, however, he hasn't posted a photo of her on his Instagram since April 2019.
