's sexting partner could be taking her "talents" to video ... 'cause she was seen strollin' around with Vivid honcho Steve Hirsch this weekend -- and we all know how that story ends.

TMZ obtained video of Sydney Leathers -- fresh off her beachside bikini romp -- getting into Steve's car as she left the Vivid  porn headquarters in Los Angeles on Saturday.
