The 53-year-old actor made a surprise appearance on Saturday night at The Comedy Store in Hollywood, California, jumping onstage with comedian Mat Edgar. Rocking a mohawk, Depp dressed casual in black jeans and a T-shirt, carrying a beverage.
Edgar himself was surprised when Depp walked onstage, which happened after the comedian told the audience that the A-lister was in the building, according to E! News. The two then reportedly bantered back and forth, with Depp joking that Edgar's 15 minutes of stage time was up.
The Pirates of the Caribbean star later posed backstage with recently divorced singer Ryan Adams and comedian Doug Stanhope. Stanhope -- a longtime friend of Depp's -- is currently being sued by Heard for defamation after the Justice League actress alleged that Stanhope accused her of blackmailing her estranged husband in a "completely false and defamatory" guest column, titled "Johnny Depp Is Being Blackmailed by Amber Heard -- Here's How I Know," which was published on TheWrap.com on May 29.
Last week, Stanhope talked about his controversial essay during his appearance on Sirius XM's The Howard Stern Show, and told the host that Depp thanked him for his words.
"I had no contact with him until he texted me after that went out," Stanhope said. "He said 'Hey, thanks for being honest.' He didn't know that was going out."
Before Depp's surprise appearance in L.A., the actor had been staying on his private island in the Bahamas since concluding the European half of his tour with his band, The Hollywood Vampires. The American leg of the Hollywood Vampires' tour begins July 1.
Meanwhile, Heard and Depp's restraining order hearing that was set for earlier this month has been rescheduled to two hearings in August. Heard was granted a temporary restraining order against Depp on May 27, after alleging that the actor was both emotionally and physically abusive towards her throughout their relationship. Depp has not directly responded to the allegations, though in previous court documents, his lawyer, Laura Wasser, claimed that Heard is "attempting to secure a premature financial resolution by alleging abuse."
