That was the speculation that sparked on the Internet after the blond beauty posted (then deleted) a photo of herself laughing and sitting on her hunky co-star's lap on her Instagram page.
Dating rumors began circulating when Duff innocently shared the fun photo of herself and Younger co-star Nico Tortorella, along with a group of pals, but E! News learns that there is nothing romantic going on here.
A source close to Nico tells us the two are not dating.
Hilary also felt the need to set the record straight and called out the media reports claiming there was anything going on between her and Tortorella on Twitter.
She wrote, "Oh daily mail guess u reporting(in detail I might add lol)on my lipsticks&sweaters weren't getting enough traction.go for the friends&co [star]s."
In the new issue of Elle Canada, the 27-year-old singer revealed how she handled all the negative attention after she and the former hockey pro announced they were separating in January 2014 after three years of marriage.
"I have a good therapist!" the cover girl laughed, adding, "I've dealt with [attention] for such a long time. But some of the bigger struggles that came my way in the past two years—like my separation or when my parents separated—were the first times I had to deal with people knowing about something personal happening to my family.
"It just felt so invasive and insensitive. It got really gross, and I think part of you gets a bit desensitized. The best way to handle it is by just owning your shit. I'm human and this is what happened. None of us is perfect."
