Of course, celebrities and fans alike took to the comments section to congratulate the newly-engaged couple, with plenty of Chris' Marvel co-stars sending their well-wishes.
But one person who many would not have expected Chris to hear from is his ex-wife, Anna Faris - who he split from in August 2017, with their divorce being finalised in October last year.
Anna, who was married to Chris for eight years and shares six-year-old son Jack with him, used the opportunity to reach out to her ex-husband and prove that you really can be friends with an ex.
