Sara De Boer/STARTRAKS PHOTO via ABCNickelback welcomed a surprise guest during their concert in Los Angeles Friday night: Chad Kroeger‘s estranged wife, Avril Lavigne. She joined her ex and his band onstage for a performance of the Nickelback song “Rockstar.” You can watch fan-recorded footage of the collaboration now on YouTube.
“You never know who will join us for ‘Rockstar’ karaoke,” Nickelback wrote on Twitter alongside a photo of Kroeger and Lavigne together.
Kroeger and Lavigne got married in July 2013. The Canadian couple announced their separation in September 2015, but they’ve continued to attend events and work on music together.
Friday’s onstage reunion also marked the first show Lavigne, who’s been struggling with Lyme disease, has played in nearly three years.
“Good to be back on stage!” Lavigne wrote in an Instagram post. “Feeling excited, happy and grateful.”
Nickelback is currently on tour in support of their new album, Feed the Machine.
