Kelsey Grammer reveals her nasty Karen Bass nickname as she endorses Spencer Pratt for LA mayor.

Kelsey Grammer is expecting Spencer Pratt, confirming the former star when she dropped off Karen Bass and Gavin Newsom as she hosted an event for US Treasury Secretary Scott Bessent.

“California is a beautiful state – it’s run horribly,” Bessent, one of Trump’s most trusted advisers, told a crowd Friday before a rally of Trump supporters at the Rustico restaurant in affluent Westlake Village, about 40 miles northwest of downtown Los Angeles.

Besent, told reporters “There is no foolproof solution” earlier in the week when asked by a reporter about the California governor’s proposal to levy a 100% Golden State tax on President Donald Trump’s new $1.776 billion “Anti-Weaponization” fund.

Grammer, who told the crowd he’s been a proud Republican for decades despite working in liberal Hollywood, described Bessent as a “star,” adding “stupid lives in California,” referring to Democrat policies that hurt the blue state.

The actor also took a swipe at the embattled Los Angeles mayor. “I just call her Karen Bass-ackwards. That’s what we’ve been calling her at my house,” he said as he left the party. He also said he would vote for Spencer Pratt for mayor.

“He’s the only guy you can choose from. We know what the others are going to do,” the “Cheers” and “Frazier” star told The Post.

Surprisingly, he didn’t have much to say when asked about Newsom, either. “I just hope we’ve heard the last of him,” he added.

Bessent is participating in a nationwide campaign to promote “Trump Accounts” that provide $1,000 to children to invest in the stock market and grow while also helping to improve financial literacy among youth.

“It’s leveling the playing field for every American,” Robin De Sapio, 47, a married mother of two from the Santa Rosa Valley, told The Post of Trump Accounts.

“These accounts are all 18-year-olds and under – they’re from America. To me, that’s exciting. We can teach financial literacy and become money wizards from scratch. This is a great idea.”

Her son, Marty, 10, is looking forward to seeing the investment grow and commented, “When you turn 18 you get a lot of money invested. It’s great. I love it.”

When he turns 18, he “saves a little, then buys a car and makes more money.”
