The 'Can't Be Tamed' singer - who is engaged to 'The Hunger Games' star Liam Hemsworth - has revealed she sometimes dreams about locking lips with the 28-year-old 'I Kissed A Girl' hitmaker and wishes they were real.
Sharing her thoughts via Twitter, the 20-year-old singer-turned-actress wrote on Sunday (13.01.13): ''Had dreams about @katyperry all night. dayummm that was a good time! #cherrychapstick need to c u more often sloot! Xxxxx (sic)''
After revealing her latest crush, Miley said she planned to spend the rest of the day helping her Australian fiance celebrate his 23rd birthday.
She said: ''It's my baby's birfffday today so no tweeting :) gotta spend that qt (quality time) gonna be on a little twitter hiatus for a bit. Love y'all xx (sic)''
Miley previously admitted she also has a crush on Katy's pal 'Twilight Saga' star Kristen Stewart and is particularly fond of her fashion sense.
She tweeted a picture of the 22-year-old 'On The Road' star in November from the London premier of the final vampire movie 'Twilight Saga: Breaking Dawn - Part Two', in which she was wearing a sparkling lace jumpsuit by Lebanese designer Zuhair Murad, and wrote: ''K Stew keeps getting better! Ughhh this look is soooo goooood! #girlcrush (sic)''.
Miley recently claimed she was in no rush to wed as she already felt married and didn't feel any urgency about walking down the aisle.
She said: ''I already feel married. I know we are forever. I don't need the paper right now.
''I don't know when we will get married yet. We are still enjoying being engaged. I've got so much planning to do with the tours and getting my record out. First I have my movie, then my record - then I'll do my wedding planning.''
