An amusing video has emerged of a fan asking Justin Timberlake to buy her a drink midway through the singer's concert in Perth, Western Australia on Thursday night.

The video, captured from the crowd by Thalia Kambouris, records the hilarious conversation between Thalia and Timberlake as the popstar was preparing to begin his next song.

After Thalia screams out 'I love you Justin,' Timberlake responds by asking 'have you been drinking?'

Thalia denies that she has, but asks Timberlake if he could buy her one, much to the amusement of the audience.

According to Thalia however, the promised drink never arrived:

"After 6 years of waiting, my dream had finally come true. I was not only able to see Justin Timberlake again, but I was also able to have a two minute chat with him. I took the liberty to scream out "I LOVE YOU JUSTIN"! And in true JT style he responded with "I love you too sweetie". At this moment my body went into shock and my heart melted. He then asked me if I had been drinking due to my outburst. He obviously doesn't know me too well - because I am loud by nature. Justin then told me to “have a drink”. In reply, I asked him to buy me one. He then said he would organise something and I was expecting drinks to be served all night. Suffice to say I'm still waiting for my vodka and lemonade. Justin - you still owe me one. But other than that, the concert was the best night ever! Simply unforgettable," Thalia wrote online.
