'Baywatch' Star -- Hammering Out a Deal w/ Chippendales

Ex-"Baywatch" star Jeremy Jackson is currently in a meeting with honchos at Chippendales in Las Vegas -- and we're told, both parties are trying to hash out a deal for the actor to join the bow-tied bunch on a full-time basis.

Jeremy's rep tells TMZ, the former child actor is on deck to fill an empty celebrity host spot ... following 98 Degrees singer Jeff Timmons -- but unlike Jeff's short stint ... this would be a long-term deal.

We're told Jeremy is extremely serious about the gig -- going to Vegas last weekend to try on the bow tie and shirt cuffs (above) just to get a feel for the experience.

And that's not it ... we're told Jeremy's also been working out non-stop to prep for the position -- and after entering "Celebrity Rehab" earlier this year for a hormone-injecting fitness addiction ... he's doing it ALL-NATURALLY.

We're told an announcement is expected to be made shortly.
