Why Kate Winslet felt up Susan Sarandon

Kate Winslet didn't ask for permission to touch Susan Sarandon's breasts at the 2016 Screen Actors Guild Awards.

The Steve Jobs star, like most people in attendance at the ceremony on Saturday, was in awe of 69-year-old Susan's cleavage which she proudly showed off to the world.

As Kate was chatting to the Tammy star and Michael Shannon at the Shrine Auditorium in Los Angeles she decided to reach in for an impromptu feel of Susan's assets and gave the red-haired actress no warning.

When shown a photo of the incident during an appearance on TV chat show Jimmy Kimmel Live!, she confessed: "Look at Michael Shannon! He's so delighted. I'm feeling Susan Sarandon's t**s, shameless!"

Jimmy then enquired: "Did you ask first?"

To which Kate replied: "No! Of course not! I'm just like, 'Hi, Susan!' "

The 40-year-old British actress also revealed Susan wasn't the only famous woman she groped at the SAG Awards.

She cheekily confessed: "I think I may have even felt Kristen Wiig's butt as well at some point."

Kate - who is married to Ned Rocknroll - also got to hang out with her Titanic co-star Leonardo DiCaprio at the SAG Awards, but she didn't grope him in any way.

The screen icon is still amazed that people are always so excited to see the pair together, almost 20 years after they played tragic lovers Rose DeWitt Bukater and Jack Dawson.

She said: "People are always so excited to see Leo and myself in the same space, which, you know, at the end of the day, that's so lovely, isn't it? It's been 20 years and people still get suck a kick out of it.

"It's really quite endearing and we do laugh about it. We were giggling about it (at the SAG Awards). I was like, 'My, God! Can you actually believe it that people get so overwhelmed by the Jack and Rose thing still today?' "
