After crushing it during her GRAMMYs performance with Metallica -- despite technical difficulties -- the Joanne singer was spotted with talent agent Christian Carino at the Interscope Records after-party at h.wood Group's Peppermint Club in Los Angeles, California, on Sunday.
An eyewitness tells ET that the couple didn't leave each other's side the whole night, but that Carino was sure to let his girlfriend take the spotlight after her big GRAMMYs night.
"There were cute moments of arm in arm and brushing each other's side," the eyewitness adds. "It was minimal PDA, but Gaga was glowing."
Gaga and Carino recently began seeing each other, a source told ET last week. The two were not shy about sharing their affection at Super Bowl LI, before the 30-year-old singer's incredible halftime show performance.
