While on the red carpet the pair discussed Megan’s birthday, with MGK saying, ‘It’s my fiancée’s birthday at midnight so we are celebrating her wonderful night,’ to which Megan replied, ‘I’m boring I don’t drink, but I’m sure he’ll go off for me.’

Not trusting the multiple cameramen snapping photos, MGK took matters into his hands and became Megan’s photographer at one point, kneeling in front of her to take photos.

The couple continued to show each other affection in front of photographers, with MGK tenderly brushing a strand of Megan’s hair at another point.

During a red carpet interview with E! Megan revealed she was feeling relaxed ahead of the show: ‘I feel great! I don’t have to do anything — I did all my work. He still has to perform.’

Meanwhile Kelly, who is nominated for top rock artist, said,  ‘I’m honored they’re letting us do a fan-favorite instead of a single. So it feels like an honor to show my artistry instead of what’s hot on radio. Appreciate that.’
