So yeah, back to the things that matter. The beef between pop star Robbie Williams and Led Zeppelin guitarist Jimmy Page over real estate has been marinating since 2013, when Williams bought a £17 million home in the same Holland Park, London neighborhood as Page. The two became bitter neighbors when Page filed an objection to Williams’ extensive renovations. Despite the guitarist’s efforts to block the singer’s overhaul of the property, it was approved this past July.

According to The Daily Mail, since construction began on Williams’ house, he claims Page has gone “mentally ill” while searching for ways to stall it again. The former boy band star asserts that Page has been sitting outside of his home for four hours at a time making recordings of the construction to see if the noise levels are too high, and even caught him sleeping in the garden trying to get a more inconspicuous vantage point to spy on the workers. “It’s really strange,” Williams said about Page. “It’s like, ‘What are you hiding? Is there something you’re hiding?’ So, so weird.”

Williams also claims that the same thing is happening to his former Take That bandmate Gary Barlow with Queen guitarist Brian May, and joked that it may be something he’ll do as an aging musician. He said, “Maybe I should apologize to Ed Sheeran for what I’m going to do to him in 15 years.”
