Actor Johnny Depp was spotted in England on Sunday where he joined British musician Jeff Beck on stage for a surprise performance as the jury deliberates in his defamation trial against ex-wife Amber Heard back in the United States.

Videos posted on social media show Depp, guitar in hand, rocking out on stage during Beck's concert, which took place in Sheffield, according to the Hollywood Reporter. Depp and Beck performed their 2020 collaboration "Isolation," the videos appeared to show.

According to the Hollywood Reporter, Depp and Beck also performed a cover of Marvin Gaye’s "What’s Going On" and Jimi Hendrix’s "Little Wing."

Depp's impromptu appearance returned him to his roots, as before he began his career as an actor, he aspired to be a musician. His musical career was short-lived, however, as he testified during his defamation trial, he found more success in acting.

Depp is also a member of the hard-rock supergroup, Hollywood Vampires, alongside Alice Cooper and Joe Perry.

The band performed at the Rock in Rio music festival in Lisbon, Portugal, in 2016, when Depp was initially facing Heard's domestic abuse claims.

The two high-profile actors wrapped up the defamation case on Friday, after days of hearings that included a testimony from Depp's ex-girlfriends Kate Moss and Ellen Barkin. It also included notable name-drops of stars like Elon Musk, Paul Bettany, Marilyn Manson and James Franco.

Movie executives were also repeatedly dragged into the discussions as both Depp and Heard claim to have lost out on film spots, in "Pirates of the Caribbean" and "Aquaman 2," respectively, due to the controversy of the case and the allegations of abuse.
