I always find Hollywood 'Christian' celebs hard to believe.
Steve Harvey hosts Family Feud, and all that show does anymore is sexual innuendo. And the show's writers clearly encourage it by the types of questions and the wording they use. and SH runs with it every chance he gets. Not to mention i recently saw a recording of him during a commercial break and he was dropping f bombs left and right.
Chris Pratt. His language. Some of his roles, such as Guardians where it starts with him forgetting the woman he had a one night stand with was even on his ship then pretty much dismissing her as irrelevant, or his sex scene in Passengers. Some of his BTS/bloopers, such as pranking a female co-worker on Parks and Rec by being completely naked when she opened a door. His marriage and divorce to Anna Farris, who i've not heard of as being a Christian.
Denzel Washington. Typical stuff, language, etc... but in Eli, a very violent movie that he pretty much wrote and directed everything. And despite this important book being the bible, at the end it showed a collection of other important pieces of literature, which included other religious books, such as the Quaran.
I've just yet to see a big name Hollywood actor, still active in popular movies, and not playing roles that contradicted their Christian claim. Some of the b-list actors seem to do a better job of it.
