The former "Hanna Montana" and Disney star said she updated her home theater system to improve her television viewing experience for when she watches "Here Comes Honey Boo Boo."

"I put in a home theater in my house, and then it wasn't quite loud enough so we got sub woofers so I can really hear her extra loud. So when I hear her, 'Holla for a dolla!' The whole house shakes," she said then laughed.

When Handler asked Cyrus if her non-stop talking character Missi on "Men" was inspired by Thompson, she smiled and replied, "Yeah, basically." Handler then asked if her fiance Liam Hemsworth ever watched the TLC hit reality show with her. 

"Liam won't watch it," she said.

After Cyrus' interview, Will Ferrell made an appearance. The mustached 45-year-old surprisingly arrived on set in a mini-buggy, which sent Handler into a fit of giggles.

Later, Cyrus tweeted a photo of herself posing with Handler's sidekick Chuy Bravo. The caption on the image read, "everyone needs their own little sidekick ❤❤❤ givin Chuy some luvvvin."
