It's Miley Cyrus' late night mystery texts.

The pop star was at the after-party, held following her controversial hosting appearance on Saturday Night Live.

It was 2:49 in the morning, and she was texting with a guy named Theo.

"I wanna see you too," she types. "Should you have your drink-y I'll get this done and come see you."

He writes back: "That sounds like a good plan-y."

Miley replied: "What time ya thinking you'll be home-y?"

The video was shot as miley sat in a Manhattan restaurant with her back to the window.

So who's Theo? He's the photographer son of Rolling Stone magazine tycoon Jann Wenner and he's a well-known ladies man. He took a photo of Miley for Rolling Stone.

Judging by their late night texts, he and Miley are turning their relationship into something more.
