Kanye For President is one supporter down.

Roseanne Barr appeared on Jimmy Kimmel Live! on Monday night, rocking some noticeably different platinum blonde hair, where she confessed to the late night host that she would not support the 35-year-old rapper's presidential ticket.

"No," said Roseanne, who ran for president herself in 2012, on the possibility of supporting Kanye, "But I will support American citizens taking an interest in their government."

"I wish more regular people would do it," said Roseanne. When Jimmy asked if that might include Donald Trump, she joked, "He's kind of irregular."

It wasn't all politics, though! Roseanne also played a game of "Name That Famous Celebrity" with Demi Lovato, and the two weren't half bad! Watch below.

One person who has a different take on Kanye's presidential bid is Rihanna, who ET caught up with in NYC Monday, where she was supportive of Yeezy's speech and candidacy.

"I mean people are voting for [Donald] Trump," Rihanna said. "Who wouldn't vote for Kanye?!"

"I got to see it," Rihanna said, referring to his lengthy VMA speech that culminated in the rapper announcing he would run for president in 2020, "and I'm really, really elated with his speech. His speech was incredible."
