Yeah, she doesn't know that though. She assumes that one the nights he's not at his place skyping with her, he's out with his friends being social.

That gets a gasp out of her. "You sing karaoke?" Because that sounds perfect. "That's what I want to do. We can go sing duets. It'll be fun." Yeah, she didn't hear anything past karaoke. "I'm not a great singer. Just a warning."

Also, if she can get him up there by himself, she's going to stand in front of the stage with her phone on lighter app and sway. If she'd known they were going to karaoke, she totally would have brought an extra bra to throw at him just to make him blush.
