Alexandra Daddario stunned on the red carpet as she arrived in Las Vegas for the 2017 Billboard Music Awards on Sunday night.

The 31-year-old Baywatch actress showed off a lot of leg and her flawless décolletage in a sexy gold number.

The off-the-shoulder dress accentuated her slender frame as she added a pair of black pointed heels to her look. 

Her rich raven locks were styled in a side parting and swept back away from her face, showing off her flawless porcelain complexion.

She added a pop of color to her look with a bold red lipstick. Her blue eyes stood out thanks to her dark smokey eye make-up and thick liner. 

Rumors have been afloat ever since her and Zac Efron signed on to do Baywatch. And now the raven haired beauty is addressing those rumors. Speaking to E! she said: 'Zac and I work together.'

'We play love interests, so I understand why people would go crazy but Zac and I are very good friends.' However, she did tease a little as she added: 'We would have very blue eyed children.'

The duo have been making a splash Down Under during their press trip to promote the new film. Despite their close friendship the pair have denied speculation that they are more than friends. 

Meanwhile, Vanessa Hudgens and Ludacris are co-hosting the 2017 Billboard Music Awards in Nevada.
