Ashley Tisdale is set to marry musician Christopher French this summer.

And on Sunday evening the 29-year-old teased a look in all-white while attending the Young Hollywood Awards in a shimmering white dress adorned with a pretty silver feather pattern.

The High School Musical star was voted Social Media Superstar, beating out the likes of Ariana Grande, Chrissy Teigen and Bella Thorne.

Ashley, who also presented the You're So Fancy award to the category's winner Bella Thorne, paired her white and silver frock with a pair of strappy silver high heels.

The blonde beauty wore her shoulder-length tresses in a sleek straight style and her makeup was sophisticated - with a brown smokey eye and light pink lips.

She kept her jewellery simple with just a pair of small stud earrings, but more noticeably absent from her arm was fiance Christopher.

Ashley started dating the music producer in December 2012 and they announced their engagement eight months later after the musician proposed at the top of New York's Empire State Building, slipping an enormous double halo, cushion-cut diamond ring on her finger.

'I was like, "OK, this is the guy." And he knew the same thing. It was just this feeling that it doesn't get any better. I can't explain it! It's just natural between us,' she has previously said.

Last year, Ashley said that she had enlisted help for the impending nuptials, telling E! News: 'I have a wedding planner so that's a lot easier.

But along with the wedding, Ashley has been kept busy with her career which has been going from strength to strength.

The series Young & Hungry which she is an executive producer on has been nominated for a Teen Choice award, news which she shared excitedly on Instagram.

'WHOA!!!! I produce that show! I know @wree!! Congrats to the beautiful @wree and Young and Hungry cast on the Teen Choice nominations! #GOVOTE'.

Fiancé Christopher also produces the music for the series, he tweeted the good news on Thursday:

'Huge congrats to the entire @YoungandHungry team on the Teen Choice nom! Proud to be part of such an awesome group on a killer show #govote'.

The ABC Family series sees Emily Osment play a feisty food blogger and sees Ashley star as Logan, a gay magazine editor.
