Just days after Kate Moss took the stand to support Johnny Depp, she appears to have opened the door to having her former love back permanently in her life.

The 48-year-old supermodel, who appeared via video link in the US-based defamation case between Johnny and his ex-wife Amber Heard, made a “surprise” appearance to watch Johnny, 59, perform with rocker Jeff Beck at Royal Albert Hall on May 31.

Kate and Johnny then met up backstage and partied the night away – looking just like old times.

“It has been so long since the two of them have been able to catch up, but they spent a good hour or more aside just catching up,” a source says.

“Johnny is super glad that this brought Kate back into his life. He would love to continue being friends with her and staying in touch with her because she is a good person who obviously has his best interests at heart.”

Kate has been happily dating photographer Nikolai von Bismarck since late 2015, so some friends are hoping she won’t be spending too much time with Johnny, who she was in an “intense” three-year relationship with from 1994.

“It took Kate years and years to get over Johnny … he’s always been the one who got away,” says a source. “But they haven’t always brought out the best in each other”. ■
