Miley Cyrus -- who has been spotted smooching Aussie actor (and Last Song costar) Liam Hemsworth -- doesn't have any plans for Valentine's Day this year.
"Work," she told UsMagazine.com when asked how she'll spend the day. "I'm really boring."
During an E! pre-Grammy show, she denied rumors that she's engaged - or that she's been wearing a promise ring. "I bought it myself," Cyrus, 17, said of the bling. "And I got it made in London, and everyone thought it was diamond when it wasn't. It was the cheapest thing ever ... So if I do get a promise ring, it better be real!"
Cyrus -- who told Us she looked forward to seeing Lady Gaga the most at the Grammys -- said she tried on three dresses for Sunday's show.
"I hate trying on clothes - I cannot do it!" she said on the red carpet. "They pin you forever."
She eventually settled on a Herve Leger by Max Azria frock.
"I like it because it wasn't stuffy," Cyrus told Us. "I wanted to be edgy."
