7:00 PM PT -- Well, we were wondering what Charlie thought of Denise's move, and Charlie told us through his rep Jeff Ballard it's short and sweet ... "Go get 'em, Denise. xox C."

Denise Richards is not only supporting her daughter's decision to create an OnlyFans account ... Mom's getting in on that action too.

Get your mind outta the gutter -- what we mean is Denise announced Thursday she's launching her own OnlyFans, a decision that comes one week after her 18-year-old daughter, Sami Sheen did the same.

Denise is charging $25 per month for access to her exclusive content ... slightly more than 18-year-old Sami's $19.99 rate.

As we've told you, Denise went toe-to-toe with Charlie Sheen over their daughter's OF, and won. Charlie was staunchly against Sami posting content on the site, where many people ... though, not all, post nudity.

Waiting for your permission to load the Instagram Media.
