During the chat, Ellen brought up Charlie‘s many shirtless photos on social media and playfully poked fun at the singer for showing off.

She also asked Charlie who he wrote “Attention” about – and he got super flustered!

“My heart’s racing right now,” he stammered. “I’m freaking out right now…it is somebody…I’m sweating right now!”
