Rihanna instantly ''fell in love'' with her voluminous Grammys gown.

The 'Rude Boy' hitmaker - who sported an enormous bubblegum pink Giambattista Valli creation at the annual awards ceremony at the Staples Centre in Los Angeles last night (09.02.15) - has confessed she knew she wanted to wear the babydoll dress, from the designer's latest couture collection, the minute she laid eyes on it.

The raven-haired beauty - who accessorised with a pair of statement diamond earrings - told E! Live From the Red Carpet: ''I'm wearing Giambattista Valli [from his] new collection. I saw this dress on the Internet and I just fell in love with it.''

The ruffled strapless gown was an unusual choice for the 26-year-old singer, who is known for her love of revealing red carpet looks after sporting a see-through embellished figure-hugging gown to the CFDA Awards last year.

Charli XCX also opted for a girly colour palette, chosing a white satin tuxedo, electric pink bow tie and fur shawl.

The 'Boom Clap' hitmaker, 22, was keen to make a statement in the eye-catching Moschino ensemble.

She said of the quirky outfit, which she teamed with sparkly pink heels: ''I hate boring fashion!''

Also turning heads on the red carpet was rapper Iggy Azalea, who showed off her curves in a classic cobalt Armani Privé gown and styled her blonde hair into plaited crown .

To tone down her bizarre up do, the 'Fancy' hitmaker opted for natural makeup, teaming dewy skin, with a nude pink lip and minimal mascara.
