Emily Blunt admits she felt sick after kissing some of her Hollywood co-stars

Emily Blunt has admitted that kissing some of Hollywood’s biggest heartthrobs made her want to ‘throw up’.

It has to be a strange concept when you get paid to kiss people who aren’t your partner, but we know that locking lips with the likes of Ryan Gosling and Tom Cruise would be at the very top of some people’s bucket list.

And Oscar-nominee Blunt revealed she has learnt how to bring the chemistry to life when she’s not quite feeling it.

Talking about on-set chemistry during an appearance on The Howard Stern Show, she said: “I have had chemistry with people and have not had a good time working with them.

“Chemistry is this strange thing. It's an ethereal thing that you can't really bottle up and buy or sell. It's there or it's not. And you can manufacture it.

“I've been doing this long enough. I could have chemistry with this water bottle at this point. You know how to conjure it.

“But it's just easier when you have a natural rapport with someone.”

She added: “I think my feeling is I've got to find something I love about everybody.

“I have to find something - even if it's one thing.

“It might be like they have a nice laugh or I like how they speak to people, they're polite. I mean, it might be something random.

“But find something you love about that person or something you love about them as the character and then kind of lean into that."

When Stern asked whether she ever 'wanted to throw up' after kissing an on-screen lover, Blunt didn't name any names but admitted: “Absolutely, absolutely... I wouldn't say it's extreme loathing, but I've definitely not enjoyed some of it.”

The actor did, however, mention one person that she had absolutely enjoyed working with.

And it’s not hard to believe that it’s none other than Ryan Gosling, who she worked with on her latest film, The Fall Guy.

Blunt said: “I love his wife, Eva.

“I love their children, and I feel like I'm very lucky to be friends with a gem of a person like him.”

Debuting to a whopping 86 percent on Rotten Tomatoes, reviews have praised the movie's stunts, as well as the core performances of Blunt and Gosling.

Distribution chief for Universal, Jim Orr, released a statement to AP saying: “We had a very solid opening.

“We are looking forward to a very long, very robust, very successful run throughout the domestic box office for literally weeks if not months to come.”
