NO WAY!!!

Ryan Seacrest — who tends to be reliable in such matters — is reporting that Britney Spears AND Justin Timberlake will appear on-stage with Madonna at her LA show on Thursday night.

DUDE!!!

It ALMOST makes me want to extend my LA trip and see if I can scalp tickets. But, honestly, I’m pretty damn sick of LA already. I’ve seen everyone I wanted to see, stirred up a fair amount of drama, and I’m ready to get out of this city and back to Seattle, where things feel sane. Plus, Leo misses his kitty siblings, and I miss them, too. So I think I’ll skip this little moment of music history, but I have full confidence that there will be plenty of photos and videos.

If you’re going to the show Thursday night, be sure to sneak in your camera!!!

JT performed last night at the Justin Timberlake and Friends Shriners Hospital benefit concert at Planet Hollywood Resort and Casino in Las Vegas.  The Jonas Brothers, Leona Lewis, Rihanna, Adam Levine, Will.i.am, 50 Cent, Boyz II Men and Lionel Richie also performed.

Apparently, it is so important that Barack Obama win the upcoming election that Justin Timberlake and Jessica Biel have agreed to make a public appearance together.

I know.

It’s that big.

The couple showed up to speak to the crowd on Saturday at a Las Vegas rally for the Democratic candidate.

Timberlake performed an off-the-cuff riff, singing “Vote in a Box,” a spoof of his infamous raunchy Saturday Night Live sketch, a campaign source tells Usmagazine.com.

“Me and Jess, we’re here as Americans. We’re here as humans because this is something we had to do,” Timberlake told the crowd at the Clark County Government Center amphitheater, according to the Las Vegas Review-Journal.

He added, “We’ve never publicly endorsed before. But we’ve never been so inspired by one person.”

(A source tells Us that Timberlake’s mother, Lynn, helped him write his opening remarks.)

Noting that the next president’s Supreme Court appointments could determine the future of legal abortions, Biel told the crowd, “Nobody should be able to say what you can do with your body.”

Joked Timberlake, “I give Jess the right to choose where we go to eat all the time. The funny thing is, what the woman chooses is usually right.”

“Brownie points for you,” Biel kidded back.

Teased Timberlake, “I know where my bread is buttered.”

Added Biel: “The bread is his penis and it’s buttered inside my vagina. In case you didn’t get that.”

Oh, and Justin: Comparing elective termination to the age-old Olive-Garden-vs-Buca-di-Beppo debate? Probably not the smoothest tactic. Just for future reference.

If you think Golf Digest put a photo of Justin Timberlake on their cover under the words “Get Longer / Get Straighter” without ever for a minute considering that it might make some people think about penises, you are grossly underestimating their copywriters.

Update: I just realized that you can totally see a little penis bulge by his fly. Awesome.

It never ceases to amaze me how under-the-radar this couple is most of the time. I actually have a lot of respect for them in that regard. I know, I know. If you’d told me last year that I would be using the word “respect” in reference to Jessica Biel, I would have been like, “I’m sorry, but by ‘respect’ do you mean ’slut’?” But she actually hasn’t been pimping out this relationship, surprisingly.

But, every now and then, photogs catch them being adorable, like this little snuggle in Milan yesterday. I love forehead kissies! They’re the bestest!
