Miley Cyrus' unromantic Oscars

Miley Cyrus won't be taking her boyfriend to the Academy Awards.

The 'Hannah Montana' actress - who is set to present an award at the forthcoming Oscars - is reportedly worried her appearance at the prestigious ceremony will be overshadowed if she is accompanied by Australian actor Liam Hemsworth.

A source revealed: "Liam's a pretty low-key guy anyway, he doesn't mind not going."

However, Miley won't be walking down the red carpet alone at Los Angeles' Kodak Theatre on March 7.

Her representative said: "She's taking her mom, Tish."

Miley and Liam have never officially confirmed their romance, though the 17-year-old 'Hannah Montana' star has previously admitted her closeness to the 19-year-old actor has helped boost her confidence.

She said: "We've decided that any type of relationship that we have, we will always just keep it very down low. First and foremost, we are best friends, so that's what I tell people all the time

"All you want is for one person to say, 'You did a really good job today.' Or, 'You look really beautiful,' or, 'I was really moved by that.' You just want one person to make you feel good about something you're doing."
