Rumors have been flying about a possible relationship between actor Kim Soo Hyun and 2NE1 member and actress Sandara Park aka Dara.

Often rumors are just a prequel to the news that a couple really is dating. That was the case with Big Bang member Taeyang and actress Min Hyo Rin. But just what started the Kim Soo Hyun and Sandara Park rumors? And why do they make a lot of sense?

Here are five reasons we think these two k-celebs might be dating.

1. They have been seen dining in restaurants alone. So far, no actual photos have surfaced of this couple dining together but both stars are easily recognizable. It would be hard to mistake them for someone else.

2. Sandara Park had cameos in two dramas that starred Kim Soo Hyun. She walked down a red carpet, playing herself in "You Who Came From The Stars," and played a celebrity variety show guest in his new drama "Producer." In "Producer" his rookie PD character doesn't have much chance to interact with her because he is busy taking care of Cindy, played by IU. But in real life, maybe he took her out to dinner.

3. They have a mutual friend. Jung Il Woo has said that Sandara Park is his only female friend. They became friends when they worked together on the drama "Iljimae together. Jung Il Woo and Kim Soo Hyun played rivals and became friends on the set of the saeguk "The Moon Embracing The Sun." And Jung Il Woo has spoken about how he likes to introduce his friends to each other. Both Park and Kim are known for their sense of humor.

4. Sandara Park was a big fan of "You Who Came From The Stars." She said she was motivated to get in shape by watching Jun Ji Hyun's character struggle with her weight. And Jun Ji Hyun's character wanted to look her best for the character played by Kim Soo Hyun. Also, 2NE1's music video for the song "Come Back Home" was so science fiction that it looked as if it was inspired by the alien-human romance. It was released shortly after the drama ended.

5. Sandara Park has expressed her admiration for various actors including Won Bin and Kang Dong Gun. But when asked about her ideal type, she said she wanted to date a younger guy.

"I'm the type to date younger guys," she said. "Since I don't think very maturely, I think I'd get along well with younger guys."

Park is 30 and Kim Soo Hyun is 27.

What do you think shippers? Is this a real relationship or a rumor?
