Ariana Grande stuns in white Versace gown as she arrives at the Grammys alongside boyfriend Big Sean 

Ariana Grande recently had her first rehearsal for her upcoming The Honeymoon Tour, and now the stunner is taking over the 57th Grammy Awards.

The 21-year-old arrived at the Staples Center on Sunday sporting a chic white Versace gown, with her beau Big Sean in tow.

The duo put on a romantic display as they walked the carpet, ahead of the One Last Time singer's Grammy performance.

Ariana sported a one shoulder flowing white Versace gown, which featured a triangular cut-out on the chest.

The hitmaker's dress featured a silver metallic panel along the left side, which was also embellished with an abstract floral pattern.

The sultry design sported cut-outs which revealed the songstress's back, down which her long brunette locks flowed from a slick-backed high ponytail.

She finished off her look with a pair of sleek white pumps with coordinating chrome heels, and a shimmery silver choker necklace.

The former Nickelodeon star sported a fierce cat eye but balanced the dramatic eye makeup with a light pink lipstick.

She was joined on the carpet by her boyfriend Big Sean - the duo confirmed their status in October - who looked dapper in an all-black Yves Saint Laurent suit.

Speaking with Ryan Seacrest as she arrived on the carpet, Ariana admitted to being a little nervous - despite having attended the awards before. 

'I'm just excited to be here,' she said. 'I never expected to be nominated in my first couple years of doing this, so it's an honor and I'm very excited. But I'm super nervous though!'

However, her beau was there to calm her down, although the rapper - who performed yesterday for a crowd at The House of Blues - insisted that she didn't need it.

'She's pretty calm. She's cool,' Big Sean gushed. 'She says she's nervous but she handles it great, man.'

The day before Ariana posted to Twitter, teasing followers about her stunning dress for Sunday's ceremony.

'i think grandps would be very pleased w my dress selections tomorrow. one of his favorite Italian designers! he'll be watchinnnn front cloud,' she said, referring to her dearly departed grandfather, Frank Grande, who passed away in July.

The star certainly gave him reasons to be proud, what with her two nominations and performance on the Grammys stage.

'Grandps would be very pleased' Ariana tweeted that she thought her recently departed grandfather would have liked her dress, sharing that she knew he would be watching her 'front cloud'

Ariana looked well beyond her Nickelodeon years as she later took to the stage in a slinky purple halter dress to perform her single Just a Little Bit Of Your Heart.

The pop princess looked demure, lit with pillars of soft purple light as she stood alone on the large stage.

Later a soft veil of fog covered the stage as Ariana finished her heartfelt ballad, a single from her Grammy nominated album, My Everything.
