Very odd.

Fifty Shades star Dakota Johnson and Coldplay frontman Chris Martin are apparently not only dating – they’re also going on holidays together.

A source told US Weekly that the two are “definitely dating.” ““They’ve gotten to know each other really well and are very comfortable from one another,” the source said. “Chris sends Dakota his music to get her opinion. It’s more than just a fling.”

Dakota and Chris were spotted together at Nick Cave’s concert in Israel last month and they were also seen having dinner with the singer at Yam Sheva restaurant in Herzliya.

According to a source, the couple “came in and they were really, really nice, like extremely nice. It was a surprise.

“I didn’t see them kiss or hold hands or anything like that. They ordered some starters and not a lot of food.”

They also went on a date at Sushi Park in Los Angeles last month, where an eyewitness reports: “Chris and Dakota walked in together and sat at a table for two tucked away in the corner. They seemed very happy to see each other and immediately jumped into conversation. She was catching him up on work and the different projects she has coming up. She was telling him where she is going to be and asking him what he thought. They both seemed to really respect each other’s opinions.

“They were flirty and laughing the entire meal. He paid for dinner and held the door for her. They both thanked the chefs on the way out.”
