Miley Cyrus puts 'dope-smoking' controversy behind her stealing the spotlight in plunging yellow gown
By Mike Larkin

Just over a week ago she was fighting off controversy after joking she was a 'stoner' at her birthday party.

But if Miley Cyrus was affected by the uproar surrounding her 'gag' about smoking marijuana, she managed to put on a brave front at a charity event in Los Angeles last night.

The Hannah Montana star, who recently turned 19, looked all grown up as she slipped into a daring yellow gown for the CNN Heroes Awards Ceremony.

Pleased: The singer was grinning like a Cheshire in the silky yellow ensemble as she posed with her handsome boyfriend Liam Hemsworth

Grinning like a Cheshire cat she showed off plenty of cleavage and d├ęcolletage in the silky canary yellow ensemble with pleated bust and embellished detailing.

She accessorised with a dripping of diamonds, including chandelier earrings and tennis bracelet.

But the singer and actress also showed a hint of her renowned bohemian side, by wearing her hair in a casual fish-tail plait.

Happy couple: With his arm wrapped around his ladylove's waist, Liam posed for several pictures with the Hannah Montana star as they made their way down the red-carpet

One of the reasons she looked so cheerful could have been the fact that she was on the arm of her hunky boyfriend Liam Hemsworth at the star-studded event.

The 21-year-old Australian actor looked dapper as he escorted her to the prestigious ceremony.

With his arm wrapped around his ladylove's waist, the couple posed for several pictures as they made their way down the red-carpet.
