The tweet was well-received, with fans writing things like, "I have a similar body type and it made me so happy to see you on Stranger Things," "Don't ever change.

The tweet came just two hours after Purser revealed over Instagram that she has joined the cast of Riverdale, The CW's new teen drama TV series that is based on iconic characters from the Archie Comics.

"SO excited to tell you all that I will be playing Ethel Muggs in the new CW show 'Riverdale,'" she gushed. "Cannot WAIT. ?? @thecwriverdale #riverdale#archie #cw."

As for Stranger Things, Purser isn't the only one from the show that was incredibly shocked by all the fan reaction she's received during its eight-episode first season.

ET caught up with her co-star, Joe Keery, earlier this month, where he explained there was "no way" he would have anticipated such success.

"It was a definite surprise," Keery told ET on the red carpet at Variety's Power of Young Hollywood event. "I mean, I read the script, loved the script and everything, and knew that everybody who was working on it was great, super-talented -- but the response has been crazy. Really crazy, yeah."
