Yes she does

"We kind of fucked earlier," she tells Mark as she gestures in John's direction, "but it's no big deal. He saved me. I thanked him. I'm married...not dead."

"And that's why you need to go to **** store? For some pills?" he asked, to which she nodded her head and squeezed John's hand as she left to go on stage.

"And make sure John here is waiting for me on the bus after the show, I need to ask him something," she tells Mark as her band begins the first song of her sold-out show.

"Look, I don't know who you are, and I don't care," Mark tells John in an accusatory tone, "but I don't need you to be the reason her marriage and career fall apart. She made one mistake. Whatever she asks you, say no. No need to cause her to make another one."
