Hollywood star <a href="https://www.thenationalnews.com/world/us-news/2022/05/27/hate-filled-depp-v-heard-trial-now-in-the-hands-of-jurors/" target="_blank">Johnny Depp</a>, awaiting a ruling in a US defamation case involving his former wife <a href="https://www.thenationalnews.com/arts-culture/film/2022/05/16/amber-heard-to-be-cross-examined-by-johnny-depps-legal-team-as-defamation-trial-resumes/" target="_blank">Amber Heard</a>, turned up on stage at a rock concert in British city of Sheffield on Sunday, surprising an unsuspecting crowd. Depp appeared with English guitarist Jeff Beck to perform music covers, including John Lennon’s <i>Isolation</i>, a track on which they collaborated and released in 2020. <i>The Telegraph</i> reports that <a href="https://www.thenationalnews.com/world/us-news/2022/05/25/kate-moss-spends-less-than-one-minute-testifying-for-johnny-depp/" target="_blank">Depp</a> is planning to join Jeff Beck for the rest of his concert dates in the UK. Jurors in Virginia deliberating the defamation claims from <a href="https://www.thenationalnews.com/world/us-news/2022/05/27/death-threats-and-humiliation-bring-depp-heard-trial-to-close/" target="_blank">Depp and Heard</a> adjourned on Friday without returning a verdict. They will resume discussions on Tuesday after the US Memorial Day holiday. On his tour of the UK, the <a href="https://www.thenationalnews.com/arts-culture/film/2022/04/28/johnny-depp-dropped-from-pirates-of-the-caribbean-over-abuse-claims-ex-agent-testifies/" target="_blank">Pirates of the Caribbean</a><i> </i>star will probably miss the climax of his bitter court battle to appear in cities including Manchester, York, Birmingham and Gateshead. <a href="https://www.thenationalnews.com/world/us-news/2022/05/23/expert-witnesses-say-johnny-depp-was-captain-of-his-own-demise/" target="_blank">Depp’s</a> UK tour appearances are reportedly causing venues security concerns, as they expect to have to manage his diehard fans and supporters of Heard, who could protest outside. <i>The Telegraph </i>reports that the <a href="https://www.thenationalnews.com/world/uk-news/2022/04/14/uks-open-iftar-2022-takes-place-on-royal-albert-hall-steps/" target="_blank">Royal Albert Hall in London</a>, where Beck plays twice this week, chose to increase security after learning Depp would be performing. Depp, 58, sued the actress for $50 million, claiming she defamed him when she called herself "a public figure representing domestic abuse" in an opinion piece she wrote. Heard, 36, countersued for $100m, saying Depp smeared her reputation when his lawyer called her accusations a "hoax". Depp fans took to Instagram and Twitter to share their views of the American actor's performance at Sheffield on Sunday. "Johnny is an absolute mad man … leaves court Friday … playing a gig in Sheffield UK Sunday … with Jeff Beck … mind blown," Twitter user @OneloveEarth said. On Instagram, one user "wasn’t expecting this … I thought he was in court but turns out he’s in Sheffield with Jeff Beck".
