Bulging out of his polo,
William Shatner showed off his sexy midriff after enjoying lunch in Somis, California this weekend.

Space is the final frontier ... for the 79-year-old's shirt.
Lin Yu Chun -- aka the male,
Taiwanese Whitney Houston -- will make his U.S., late night debut on "
Lopez Tonight" ... and because everything is better with a little
William Shatner, they're doing a duet.

The rest of the sure-to-be-epic performance airs tonight at 11PM on TBS.
Can you guess
whose holly, jolly mid-section was spotted basking on the beach in Hawaii?
As the old saying goes, "What's good for the rogue governor, is good for the Star Trek captain."
William Shatner has been doing inspired readings of
Sarah Palin's autobiography "
Going Rogue" on "
The Tonight Show with Conan O'Brien" -- but last night it was Palin's turn to read from Shatner's.
Neither book is likely to receive a Nobel Prize in the near future.
Levi Johnston is furious over a
William Shatner skit on Wednesday's "
Tonight Show"-- in which Levi was made to look like a racially insensitive pothead -- claiming the outrageous Twitter posts Conan attributed to Levi were fake.
Rex Butler -- Levi's lawyer -- tells TMZ the Alaskan is demanding a retraction from
NBC. What really pisses Butler off ... before Shatner's dramatic reading of Levi's putative Twitter page, Conan said: "All real ... we did not make these up."
Butler says the Twitter page is NOT Levi's and that, "We are in the process of dealing with Twitter first. I think they have an obligation once something like this happens to make some kind of corrective measure."

Among the Tweets that were read poetry-style by Shatner ... "Anybody know where I can get some good weed" and "Whats the deal with the taxi drivers not speaking English, is there a law against it?"
So far, not a tweet from NBC.
"Star Trek" star
William Shatner, 78, posed alongside
Captain Kirk at Madame Tussauds in Hollywood on Wednesday.

Only one is made entirely of wax.
William Shatner showed off his dewy, overexposed flesh outside a cafe in L.A. on Wednesday.

Pretty in pink.
William Shatner couldn't get outta Regis & Kelly fast enough yesterday -- and the
Shat hit the fan when he blew off the loudmouth autograph hounds waiting outside who started calling the "Star Trek" legend "Captain Jerk."

Not the best way to treat a guy whose show just got the ax.
He started the conversation yammering nonsense -- then he made it clear he wasn't Jessica Alba.
And thank goodness ... he wouldn't look quite as good in those "Sin City" chaps.
William Shatner beamed into Long Beach, Calif. for the opening of "Star Trek -- The Tour" last week -- and posed with one of the suits he wore in the series nearly 40 years ago ... while wearing a rhinocerosish leather jacket.

Shatner did not fit into J.J. Abrams new "Star Trek" movie.
Christmas came early for Trekkies when Mr. Spock and Captain Kirk were snapped together at the Spike TV Scream Awards in L.A. on Friday. Beam us up, Scotty!

Both are 76-years-old, but Leonard Nimoy and William Shatner have not yet reached the final frontier!
Set phasers to stunned.
