The new teaser for the 12th season of Keeping Up with the Kardashians hit the web yesterday, and in it we see Rob Kardashian on camera for the first time in, well, years!

"Welcome home!" mom Kris Jenner tells her son. "Do you love it, do you love it, do you love it?!" We don't hear Rob's reply, but he is smiling in the clip...

And he's not the only one who made an appearance on the show. Lamar Odom is back too! In one very intense scene, we see Kourtney and Khloe Kardashian in the car with Lamar on the way to Kanye West's fashion show, and Kourt says, "People's prayers for you saved your life..."

We hate to admit it, but we can't WAIT to watch this!
