What's more shocking: That an A-list celebrity made soap with her bathwater, or that the soap is now re-selling for thousands of dollars online?

The internet is divided over a recent marketing gimmick involving Sydney Sweeney, who, in collaboration with the men's personal care company Dr. Squatch, authorized the creation and sale of bars of soap containing, among other things, her bathwater.

Yes, this is real. In fact, the actress told E! News at the "Echo Valley" premiere earlier this month it was actually her idea.

"I think that's it's more fun to see everybody else talk about it," Sweeney said, when asked for her reaction to the soap.

Dr. Squatch made 5,000 bars of the soap − dubbed Sydney's Bathwater Bliss − and sold them online for $8 each. They quickly sold out, and now those bars are getting re-sold for much, much more on eBay. Some are priced as high as $1,600.
