Why you may ask? Well, Rogen is now feeling the pressure to propose to his long time love because he would always compare his relationship to Ford's and Flockhart's but now since Harrison built the courage and proposed, he feels like the pressure is on.
Rogen says, "They were my couple. I was like, 'They're not engaged, they are just happy to be together'.
"Now, if Kurt Russell and Goldie Hawn get engaged, I'm f**ked."
Why is it such a big deal for men to propose to the love of their life? Guess it will be one of those things that women will never get the answer to.
