Bravo's Watch What Happens Live has a new set and only ET got a tour from host Andy Cohen.
"Everything in here means something to me," Cohen tells ET.

The clubhouse has a little more elbow room than the previous set and features a new secret entrance and two chairs from the original set of The Oprah Winfrey Show.
"Oprah, you have to come back, because I have a surprise for you," Cohen says. "We bought the chairs online. They were about 500 bucks each, well worth it."
But perhaps the most significant updates are the random pop culture artifacts that litter the shelves.
"We got Lindsay Lohan's old cigarette," Cohen says. "We've got Tamra [Judge] from the Orange County Housewives, her last set of implants. She donated them to the clubhouse."
The former executive VP of Bravo also has personal trinkets that he's used to decorate the new space.

"People who know me know I love the Grateful Dead. This is a Grateful Dead dancing bear in Lite Brite form, which I think is super cool," Cohen says. "I just sent John Mayer a picture of that and he's going nuts over it. These are my Childcraft encyclopedias from growing up. These are from my basement in St. Louis growing up."
Justin Timberlake, Beyonce, Madonna and Katy Perry top Cohen's list of dream guests for 2017, but it was past guest Mariah Carey who was the topic of discussion during our set tour.
After the diva's disastrous New Year's Eve performance, which her reps have blamed on "technical difficulties," Carey tweeted a response, writing, "S**t happens. Have a happy and healthy new year everybody! Here's to making more headlines in 2017."

"I thought her response to what happened was perfect," Cohen says. "I thought it was awesome."
When Carey stopped by WWHL last month, she threw major shade at Demi Lovato and Ariana Grande while reaffirming she still "doesn't know" Jennifer Lopez.
