And Jenny confirmed the suspicions in a tweet in November, when she described Chris as being "dreamy".
She wrote on the micro-blogging website: "My boyfriend does many dreamy and generous things but number 1 in my mind right now is how he celebrates my new turtlenecks/let's me show him my online shopping spoils and cheers me on. (sic)"
In spite of their turbulent romance, Jenny has always been keen to praise Chris in public.
But the 35-year-old beauty admitted that, ultimately, Chris' level of fame and success played a role in their love troubles.
She shared: "We're really, really different.
"Chris is a very, very famous person. For him to go to a restaurant is totally different than for me to go. I sit in my window and I say 'Hi'
to people on the street. I have more freedom because I'm not Captain America. I'm mostly a cartoon."
Following their first split, Jenny claimed that ending their romance had helped her to return to normality.
She said: "This is what I needed to do to feel normal. To be alone."
