It’s been months since ex-Prince Andrew was stripped of his official titles, but his drama with the royal family isn’t done yet.

A source told Heat World UK in a report published on December 22 that Andrew has “become completely fixated” on Prince William’s wife Kate Middleton as the reason for why he lost his royal titles and was essentially exiled from the family. (Buckingham Palace announced in October 2025 that Andrew would no longer be known as “Prince Andrew” and that he would be moving out of his residence at Royal Lodge. The palace also confirmed that all royal “style, titles, and honours” Andrew previously had would be removed.)

“Andrew has become completely fixated on Kate. He keeps going on about how she’s a ‘silent assassin’ who’s been quietly pulling the strings and whipping William into a frenzy about him,” the insider said. “He’s absolutely certain that major decisions about his future have been run past her and William, but instead of blaming William for getting him forced out he’s turned his wrath on Kate.”

The source continued, “He has this warped belief that William is being controlled by her, that she’s whispering in his ear and turning him against his own blood. He’s saying she’s poisoned the well against him.”

According to the insider, Andrew is especially hurt by Kate because he believed they were on “good terms” before his royal exile. “What makes it sting even more for Andrew is that they used to be on perfectly good terms, she was always very polite and warm, he believed she genuinely liked him,” the source said. “Now she won’t give him the time of day and he’s seeing it as her deliberately freezing him out and using her influence to make sure he stays sidelined.”

The insider continued, “He’s now lashing out and telling anyone who will listen that she’s the reason he’s been booted from his own family. He’s vowing to get back at her, which is not going to go down well with William when he finds out.”

The source also claimed that Andrew’s “bitterness” has led him to find someone to blame for his exile, and that person happens to be Kate. “Andrew is absolutely seething and looking for someone to blame, and in his mind Kate has become the perfect villain,” the insider said. “He’s convinced himself she’s far more powerful than she lets on, that she’s quietly steering decisions behind the scenes while maintaining this serene public image. He’s a very bitter man.”

The source continued, “True to form, Andrew refuses to accept that his own actions landed him where he is now. Instead, he’s badmouthing Kate and, while there are still a few people within the palace that speak to him, he’s been venting to them and warning them not to be fooled by her ‘nice girl’ act.”

The insider also claimed that Andrew feels negatively toward Kate because of her close relationship with his late mother, Queen Elizabeth, which he believes he should have had. “He resents that Kate has emerged as this central, respected figure while he’s been pushed into total irrelevance’” the source said. “In his mind, she’s stolen the authority and standing he believes should have remained with him as the Queen’s son.”

As for Kate, the source denied that the Princess of Wales has been leading a “campaign” against Andrew, though he has been “disgusted” by reports of his association with convicted sex offender Jeffrey Epstein. “From Kate’s side, she’s simply not engaging with Andrew. She’s by no means on some campaign against him but naturally she’s disgusted by his behaviour and agrees with the King’s decision.” the insider said. “It’s very awkward for her so she’s avoiding Andrew and saying she’s glad he’s out of her hair. Andrew is so narcissistic he can’t understand why she would want to distance herself.”

The source continued, “Instead of having a shred of self-awareness he’s turned it into this big sob story whereas usual he’s the big victim.”
