Eileen, 60, shared footage from a table read of her movie 7 Days to Vegas that costars her hunky husband Vincent Van Patten.
Lisa Rinna took part in it along with sisters Kim and Kyle Richards.
The mood in the room appeared to be jovial even though Kim, 54, and Lisa, 56, have had a rough history with one another.
The footage gave RHOBH fans hope that Eileen will return for season ten.
"Call me delusional but is this a hint you’re coming back to RHOBH," one fan wrote in the comments section.
Eileen was part of RHOBH as a full-time cast member from season five to seven. She appeared as a guest for the show's eight season.
