Mariah Carey hopped the pond and found herself outside the Dorchester hotel in London earlier today. While what she's doing in the UK is anyone's guess, she was certainly friendly with fans and photographers before checking into her hotel room.
While Mimi's been a full-time mother after the birth of her twins in April 2011, she's recently teased fans on Twitter about new music.
"So.. Summer 2012.. Been in the lab, mixing up some concoctions for you, hope you like it!!" she tweeted.
A few days later, she followed it up with the equally ominous: "still working in the studio with friends o plenty! I love love this new song: )"
The last musical effort by Mariah was a collaboration with Justin Bieber last year, a remake of her song, "All I Want For Christmas Is You."
