She never fails to make a statement with her unique style.

But Lady Gaga opted for old school glamour as she shimmered in a plunging metallic gown at the Grammy Awards on Sunday.

The 28-year-old pop diva was accompanied by her handsome collaborator 88-year-old Tony Bennett.

Oozing glamour: Lady Gaga stunned in a silver gown as she hit the red carpet at the Grammy Awards in Los Angeles on Sunday

Her gown – a custom Brandon Maxwell – displayed maximum cleavage and a seductive thigh-split showed plenty of leg.

Gaga’s locks were a silvery platinum blonde to compliment her dress and for more shimmer she sported metallic grey eye-shadow and lashings of eyeliner.

Lorraine Schwartz emerald jewelry completed her ensemble for classic Hollywood elegance.

Gaga and Bennett’s duet album, Cheek to Cheek, won best traditional pop vocal album and E! host Ryan Seacrest was the first to congratulate the pair.

‘Thank you so much, we’re so happy!’ Gaga exclaimed as they hit the red carpet before the ceremony.

Bennett also explained how the two very different artists have bonded over the last year, saying: ‘We get along great. We’re both Italian-Americans and we understand one another.’

In a rather awkward moment just minutes later, Gaga blanked host Giuliana Rancic when the presenter yelled ‘Hello Lady Gaga!’, and glided straight past surrounded by her huge entourage.

Gaga and Bennett will be taking to the stage to perform during the evening among a host of other stars.
