Miley Cyrus dreams about Katy Perry

It appears actor Liam Hemsworth has some competition for the attention of his fiancee, Miley Cyrus.

In a tweet posted on January 13, the "Hannah Montana" star admitted she "had dreams about Katy Perry all night. dayummm that was a good time! #cherrychapstick"

But Miley also quit the micro-blogging site temporarily to focus on spending some quality time with Liam who was then celebrating his birthday.

Last year, the singer/actress also took to Twitter to compliment her fellow star Kristen Stewart saying, "K Stew keeps getting better! ughhh this look is soooo goooood! #girlcrush".
