During a recent concert in Brooklyn, Finneas surprised fans by kissing his male guitarist, Ricky Gourmet, on stage. 

The 26-year-old musician, known for his heterosexual orientation, also brought his girlfriend, Claudia Sulewski, on stage for a kiss. 

Finneas, who recently released his second studio album, is set to kick off a 35-date tour in January.

Meanwhile, Billie is currently on her own tour without her brother.

Fans accused Finneas of queer baiting. X user @publicimageItd wrote: ‘Aw… siblings that gaybait together stay together.’
