Harry Styles and Erin Foster More Than Friends? "They Are Casually Dating," Source Says

Sorry ladies, but this cutie might be off the market.

One Direction hunk Harry Styles was recently spotted picking out a gourd for the Halloween season alongside blond beauty Erin Foster, and what was initially considered to be just two pals hanging out at the pumpkin patch and gearing up for a festive holiday may actually be something a little more.

A source tells E! News that the twosome have a romantic relationship going on right now, but adds that it's "nothing serious."

The insider continues, "It's unlikely it will ever become serious, but they are casually dating whenever they are in the same place at the same time and it works for both of them."

Meanwhile, their outing was PDA-free and didn't seem to hint that any sort of romance was brewing. Styles and Foster, who has appeared and Nicole Richie's VH1 reality series Candidly Nicole and once dated Samantha Ronson back in 2011, did have a successful trip, though.

The stars were photographed walking out together with a nice orange pumpkin in each of their possession.

Regardless of Harry and Erin's status, the 1D singer is definitely getting hot and heavy with someone--at least, in the fan fiction story that was written about him. Anna Todd is the 25-year-old Army wife and author behind After, a book inspired by Styles that has generated one billion (!) reads online and is being called the next Fifty Shades of Grey.

In fact, Paramount Pictures has just bought the screen rights to the book, and Adam Shankman and Jennifer Gibgot have signed on to produce the movie.

"There are definitely sex scenes. I mean, I was writing it for myself," Todd told E! News. "There are adult scenes in the story. There is no S&M. They are regular sex scenes, but very detailed. It's the vanilla version of Fifty Shades of Grey!"

Sold.
