The Wikipedia entry on her personal life (or lack thereof) is pretty brutal.
Coulter has been engaged several times, but she has never married and has no children.[28] She has dated Spin founder and publisher Bob Guccione Jr.[49] and conservative writer Dinesh D'Souza.[178][179] In October 2007, she began dating Andrew Stein, the former president of the New York City Council, a liberal Democrat. On January 7, 2008, however, Stein told the New York Post that the relationship was over, citing irreconcilable differences.[180]In 2013 it was reported that Coulter was dating actor Jimmie Walker. Coulter responded to the rumors by saying "He’s the one spreading that [dating] rumor! No, we’re great friends. We do a lot of stuff together. … He is so hilarious, so I see him a lot when I’m in L.A., but we are not technically dating.” In 2017, Norman Lear, who created the television sitcom Good Times in which Walker starred on, said of Walker "I love him; he’s a wonderful guy. But I’ll tell you something about him that’ll astound you: He dates Ann Coulter.” Coulter responded to Lear's comments by saying "This rumor spreads every now and then, but it’s never been true. We’re great friends. He’s hilarious and a Republican. Now, that’s news!”[181]
Kellyanne Conway, who refers to Coulter as a friend, told New York magazine in 2017 that Coulter "started dating her security guard probably ten years ago because she couldn't see anybody else".[182]
Coulter owns a house, bought in 2005, in Palm Beach, Florida, a condominium in Manhattan, and an apartment in Los Angeles. She votes in Palm Beach and is not registered to do so in New York or California.[183]
I like the chapter in World War Z where the narrator is at a compound full of celebrities when the zombies breach, and sees Bill Maher and Ann Coulter frantically fucking before the end.
