Kissing was so good that almost all of them ended up dating or getting married to each other.
If you've ever wondered how actors can act in steamy scenes and not fall in love with each other, then these celebrities will prove that sometimes even such professionals like them can fail in the mission.
Here is the list of actors whose on-screen chemistry pierced their hearts and left a lasting impact on them.
1. Emma Stone and Andrew Garfield
Emma and Andrew's on-screen love story in The Amazing Spider-Man translated into a genuine real-life connection. Their instant chemistry was evident from the moment they met on set, and both actors openly expressed their enjoyment of kissing each other and working together.
2. Kit Harrington and Rose Leslie
The Game of Thrones stars began dating after playing on-screen lovers on the show. Harrington later confessed that during the filming of the series, especially after the steamy scenes filmed in Iceland, he fell in love with Leslie. So apparently they never left the cave.
3. Zac Efron and Zendaya
Both Zac Efron and Zendaya insisted that their characters' kiss in The Greatest Showman was special to their characters. While Zendaya stated that the kiss was significant because of their characters' forbidden love, Efron declared that this on-screen kiss was his favorite kiss ever, citing the intense chemistry and tension between their characters.
Well, we guess some of them enjoyed kissing their co-star a little too much.
4. Ryan Reynolds and Blake Lively
One of the most genuine and fun family couples in Hollywood, they started their journey together with a kiss on the big screen in Green Lantern. Although both actors were in relationships with other people at the time, they reconnected as friends after their breakups.
Lively has since revealed that she knew they would be together forever after their first kiss. Women's intuition always knows best.
5. Leonardo DiCaprio and Kate Winslet
Though after the release of the disaster movie Titanic, many fans were hoping for a romantic relationship between Kate Winslet and Leonardo DiCaprio, in real life, the actors remain good friends and unconditional supporters of each other as they have developed a strong friendship over the years.
However, it is a well-known fact that DiCaprio considers Winslet to be his favorite leading lady to kiss. No surprise there — have you seen the deleted scene of their steamy kiss in the boiler room? Whew!
