Dua Lipa is on the ’90s alt-rock bullshit right now. She’s been singing a different cover at every show on her current tour, and sometimes those covers involve surprise guests like Gwen Stefani and Lenny Kravitz, as well as non-’90s alt-rockers like Lionel Richie. On Sunday night, Lipa played San Francisco’s Chase Center, and she did it all again, bringing out Green Day leader and local hero Billie Joe Armstrong.
