Sheffield, UK - Johnny Depp made a surprise appearance on stage with musician Jeff Beck during a live performance on Sunday in the UK.

Johnny hopped across the pond for a jam session, perhaps in celebration of the end of closing arguments in his bombshell defamation trial against ex-wife Amber Heard.

The show took place at Sheffield City Hall, which tweeted a video on Monday of the rare event.

"Well...what a surprise we got last night when Johnny Depp joined ⁦@jeffbeckmusic⁩ on stage," the venue stated.

"Wishing @jeffbeckmusic⁩ good luck for the rest of his amazing tour and a big thank you to Johnny Depp for joining us!"

The actor is seen in the video playing a 12-string acoustic guitar alongside Beck, who is ripping through a solo on an electric guitar.

Depp is no stranger to rock music. In 2012, Depp and rock legends Alice Cooper and Aerosmith's Joe Perry started the supergroup Hollywood Vampires. To date, the group has released two records, its last being 2019's Rise.

Depp's explosive six-week trial against Heard, in which he is suing her for $50 million for defamation and damage to his Hollywood career, ended on Friday.

Deliberations over the defamation case are set to resume on Tuesday.
