Serena Williams Takes Sexy Booty Pic During Pottery Sesh -

Betcha didn't think pottery could be so appealing ... but, here's Serena Williams to prove it's definitely possible.

The tennis superstar put more than just her clay curves on display at a pottery studio on Thursday ... rockin' a leopard print shirt and some jean shorts that would make Daisy Duke proud.

Serena -- a Jehovah's Witness -- doesn't celebrate holidays, so she hit up Avenue Pottery in South Florida with some friends for GALentine's Day instead!!!

PRETTY POTTERY

Serena picked out the matching outfits with her friend ... and posted about the experience, saying, "I’m really getting into pottery."

Of course, Serena addressed not celebrating holidays when her baby, Alexis Olympia, turned 1 back in September ... saying, "Olympia doesn't celebrate birthdays. We're Jehovah's Witnesses, we don't do that."

Williams' hubby certainly doesn't seem to mind not celebrating V-Day ... saying, "Those pottery skills tho" with a set of eye emojis.

Yeah, dude. Pottery skills.
