TMZ Tours

Vanna White is awesome!!! She jumped on the TMZ Celebrity Tour Bus Saturday in the middle of her ice cream run, and who knew her son was so hot!

Vanna and 29-year-old Nikko had just hit up Jenni's Ice Cream shop in Bev Hills when our tour guide spotted her. Vanna jumped on the bus and had loads of fun with our guests.

TMZ broke the story, she's demanding at least half of what Pat Sajak makes if she'll continue her more than 40-year reign on the show. Pat makes around $15 million -- Vanna makes $3 mil and hasn't gotten a bump in 18 years. Remember, even "Wheel" refers to her and Pat as "the stars of the show," not distinguishing between the two.

If Vanna exits at the same time Pat hangs it up, it leaves the show without any familiar faces.

Everyone connected to the negotiations has gone radio silent, although a few weeks back a source with direct knowledge described the negotiations between Vanna and Sony as "very difficult."

Keegan-Michael Key joined a very lucky group on the TMZ Celebrity Tour ... offerin' up advice on how award shows can evolve so comedy bits don't drag people down.

Keegan hopped on our bus in Bev Hills ... and as his wife and writing partner Elle kicked it on the sidewalk, he offered up some tips on cringe-worthy humor during these awards shows.

KMK put it plainly -- you can make a killer joke that has a positive message ... but bringing someone down should be out of bounds.

He's pretty clearly referring to last week's Emmys ... where Jimmy Kimmel was dragged for "passing out" on stage as Quinta Brunson accepted her award for Outstanding Writing for a Comedy Series.

After finishing his TMZ Tour "Ted Talk," he entertained passengers with a throwback from 'Key & Peele' ... breaking out his substitute teacher character that he debuted a decade ago!!!

Sometimes guests on the TMZ Celebrity Tour get not one, but TWO extra special surprises --just ask the folks who had run-ins with Jamie Foxx and Lizzo!

First, it was Lizzo outside The Hollywood Roosevelt -- she just dropped her album "Special" last week -- and likely has a ton of promos to get done, but she still took a little time to chat it up with bus passengers ... even spilling on her favorite song from the album.

Then it was Jamie Foxx, who bus passengers spotted outside Avra in Beverly Hills.

The Oscar winner seemed to be catching up with a friend outside the celeb hot spot and gave our bus a friendly wave before joking he was going to hop on board.

Super pregnant Khloe Kardashian and super momager Kris Jenner just gave fans on the TMZ Celebrity Tour bus a huge thrill and, we'll be honest, they gave us what's known as a money shot.

Khloe and Kris were out Wednesday in WeHo flanked by security as they hit up a couple of baby stores -- on account of the whole fam being in birthing mode. We asked Khloe if she and Tristan Thompson are going with a "K" baby name, and just then it happened -- the TMZ tour bus pulled up, shocking everyone on the scene.

Check out the vid ... we talked Kim and Madonna with Kris, who seemed to have a case of the giggles. Khloe was also amused when he talked about her Kardashian kid being a family record-setter.
