Miley Cyrus was spotted yesterday frolicking in a hotel pool with what appeared to be some random guy, leading to speculation that perhaps her relationship with Liam Hemsworth— remember, they just got engaged— might be on the rocks.

Well, no dice there.

According to Cyrus' rep, the mystery man's name is Cheyne Thomas and he's a friend and part-time assistant to Miley.

And the 19-year-old star is kind of pissed that the press is jumping to conclusions about her. She took to her Twitter account and let her thoughts be known.

"So now because I am engaged I can't have a friend of the opposite sex?" she wrote. "Can't have a friend help me out while I'm working alllll day? #dumb."

She continued: "maybe YOU would have friends too if you'd get your face out the tabloids & start living your own life :) unfortunate."

Even her mom, Tish, got in on the act.

"So sad that the nasty tabloids have to make up stories to sell their trashy mags," Tish tweeted. "Cant they just leave these 2 alone and let them be happy?"

To which Miley replied, "@tishcyrus I love my fiancé & he loves me. All the rest is bull s--t. We get to live a life of happiness no one can take that away from us!"

We're happy for you, Miley.
