Several years later, Ryan told the Times, "I had two of the greatest girlfriends of all time [Sandra Bullock and Rachel McAdams]. I haven't met anybody who could top them... Show business is the bad guy. When both people are in show business, it's too much show business. It takes all of the light, so nothing else can grow." Gregg DeGuire / WireImage / Via Getty 4. Gifted costars and onscreen love interests Chris Evans and Jenny Slate dated from mid-2016 to February 2017. Then, they reconciled in November, but four months later, it was over for good.

In 2017, Jenny told Vulture, "I remember him saying to me, 'You're going to be one of my closest friends.'

If you are a woman who really cares about her freedom, her rights, her sense of being an individual, it is confusing to go out with one of the most objectified people in the entire world." Variety / Penske Media via Getty Images Chris's intense level of fame caused Jenny, who was used to being able to lead a semi-normal life, a lot of anxiety. She also hadn't processed her separation from her husband at the time, Dean Fleischer Camp, as much as she needed to. She said, "I just didn't have the tools. And I didn't think very hard ab
