WASHINGTON — Bill Clinton’s longtime personal aide Doug Band savaged Chelsea Clinton as a “spoiled brat” who created unnecessary problems because she hadn’t found her “focus in life,” according to bombshell emails released Monday.

“I’m . . . starting to worry that if this story gets out, we are screwed,” Band wrote in an email to top Hillary Clinton aides Cheryl Mills and John Podesta in late 2011.

It’s not clear what story Band was referring to, but at the time, he and Chelsea were battling over whether he was using his Clinton connections to further his business interests.

Turning his fire on the former (and perhaps future) first daughter, Band complained about Chelsea meddling in his consulting firm, Teneo, where Bill Clinton served as a paid adviser.

“I realize it is difficult to confront and reason with her but this could go too far and then we all will have a real serious set of other problems,” Band whined in a Nov. 12, 2011, email.

“I don’t deserve this from her and deserve a tad more respect or at least a direct dialogue for me to explain these things. She is acting like a spoiled brat kid who has nothing else to do but create issues to justify what she’s doing because she, as she has said, hasn’t found her way and has a lack of focus in her life,” he added.

Chelsea, 36, became significantly more active in the Clinton Foundation in 2011, taking a formal role on the charity’s board; Band left in 2010.

Another set of emails shows Band and Chelsea were at war over the connection between the foundation and his business.

In a December 2011 email to Podesta and others, Chelsea said two people separately approached her at a London event for the Clinton Foundation to express concern that someone representing Teneo clients was calling members of the British Parliament “on behalf of President Clinton.”

“Which would horrify my father,” Chelsea said.

Band wrote back that Chelsea was “more concerned” about an article in The Post about Teneo and one of its clients, MF Global, than about the health of two senior Clinton Foundation officials — one of whom threatened to kill herself.

Band said he had to talk foundation COO Laura Graham out of driving her car into the waters off Staten Island because she was under such stress caused by “wjc and cvc as well as that of her family.” The reference appears to be to William Jefferson “Bill” Clinton and Chelsea Victoria Clinton.

“She was on staten island in her car parked a few feet from the waters edge with her foot on the gas pedal and the car in park. She called me to tell me the stress of all of this office crap with wjc and cvc as well as that of her family had driven her to the edge and she couldn’t take it anymore,” Band wrote to Mills, Podesta and Justin Cooper, the aide who helped set up and maintain Hillary Clinton’s private email server.

Band said he reached Graham’s brother and her shrink, and Graham pulled back. She was the foundation COO and is now an adviser to the foundation.

Band also wrote how “stress” at the Clinton Foundation directly caused “very serious health issues” for board Chairman Bruce Lindsey.
