Beyoncé was supposed to headline Coachella this year, but her twin pregnancy complicated those plans a bit. Last week, she announced that she would be postponing her Coachella appearance until 2018, and now we know who’s filling in for her this year: Lady Gaga. Billboard reports that Gaga is set to headline Saturday 4/15 and 4/22, bringing her massive stage production with her. She will be the first woman to headline Coachella since Björk in 2007.
