Eric Dane’s alleged girlfriend was ‘blindsided’ by his red carpet debut with Janell Shirtcliff: ‘They never broke up’

Eric Dane’s alleged girlfriend, Priya Jain, was “blindsided” by his red carpet debut with Janell Shirtcliff, Page Six has exclusively learned.

“They never broke up,” a source told us Thursday.

The actor, 52, brought Shirtcliff to Wednesday’s Los Angeles premiere of his new series, “Countdown,” with a source claiming to “Entertainment Tonight” that “the two have been in an on-and-off relationship for over three years and care deeply for each other.”

However, we’re told it was the first time Jain, 27, had ever heard of the director, 41.

Our source said Jain, who has been photographed with Dane multiple times, met him last summer and that they became “exclusive” in November 2024 — right before he was diagnosed with amyotrophic lateral sclerosis (ALS).

He announced his diagnosis in April.

According to our source, Jain was “devastated by the diagnosis” but stood by the “Grey’s Anatomy” star’s side. Interestingly, ET’s source claimed that “Eric asked Janell to be there for him during this time, and she wanted to show up for him.”

We’re told that since Jain and Dane met, she has spent almost every night at his house, where she has tons of clothes.

Our source added that the actress has even spent time with Dane’s kids — daughters Billie, 15, and Georgia, 13 — whom he shares with Rebecca Gayheart.

Gayheart, 53, has since clarified that she and her on-again, off-again husband are “staying a family” and remain the “best of friends.”

Not only did Jain and Dane get matching star tattoos late last year, but the “Euphoria” star also gave her a tattoo with an at-home tattoo gun shortly after, we’re told.

Our source added that the last time they saw each other was this past weekend, while the last time they were photographed together was mid-May.

Reps for Dane, Jain and Shirtcliff did not immediately respond to Page Six’s requests for comment.
