Footage taken from the social media platform, Snapchat, surfaced showing the 30-year-old with an unknown brunette on the street.
The grainy video was taken by bystanders who captioned it with: 'So no-one wins [The bachelor] new chick in town'.
A bystander told the Daily Mail that Cummins didn't appear to be "hiding anything" and they were certain this woman wasn't one of the contestants from the season.
"I've been watching The Bachelor and [the woman] was definitely not one of the contestants. She was way too short to be Brittany," they said.
"They didn't kiss or cuddle, but their body language was close. It kind of seemed like they'd been out for dinner and were saying goodbye at the end of the night."
Cummins' manager, Josh White, has defended the photographs, saying the rugby star is often approached by members of the public.
"As you can appreciate, Nick is a well-known public figure and gets stopped by both men, women and children in the street multiple times a day and night wanting to chat or take a picture," he said in a statement.
Hmm, jury is out but it does seem the evidence that the Honey Badger and his leading lady are no longer together is growing...
