Emma Watson and fellow actor Johnny Simmons touched off torrent of speculation about a romance after they were spotted kissing and hugging. But there may be less to their relationshikp than meets the eye.

Watson, 21, and Simmons, 24, filmed “The Perks of Being a Wallflower,” a relationship movie about love and finding your place in the world.

Emma plays Sam Patrick who introduces high-school freshman Charlie (Logan Lerman) to the worlds of drugs and sex.

Simmons has a minor role in the ensemble movie, playing Brad.

In June, Watson and Simmons were spotted at a park in Pennsylvania, but her spokesperson strongly disputed reports of a romance, calling them a “complete fiction.”

Watson and Simmons were spotted again at a restaurant in California earlier this week and were photographed kissing and hugging.

Britain’s tabloids were quick to fan the flames of a relationship.

“They were all over each other, kissing and hugging. It was very sweet to see. She looked utterly besotted… They’re obviously head-over-heels in love,” a source reportedly told London’s Daily Mail.

‘The moment Johnny turned up Emma was all over him. He stayed overnight at least one night this week. It is clearly a serious relationship,” the source said.

A number of people spent the night, not just Simmons.

Emma has lamented publicly how hard it is to find a boyfriend and feels isolated by a “fame wall.”

So, she may be going out of her way to spark a relationship, and locationships on movie sets are not uncommon.

But a closer examination of the photos suggests that Watson and Simmons are more likely very good friends.

Watson’s lips are pursed and held tightly together, like she’s kissing her cousin.

Actually, it looks like a movie kiss.

His kiss looks about the same. Their lips aren’t even really meeting.

Unless they are really inexperienced or bad kissers, the whole thing looks a little too stiff.
