Justin Timberlake has told fans he's ''not even close'' to being done after being honoured at the MTV Video Music Awards last night (25.08.13).

The 32-year-old singer picked up four prizes at the annual event - including a lifetime achievement gong titled the Michael Jackson Video Vanguard Award - but insisted the triumphant evening only marks the beginning after he made his return to music earlier this year following a hiatus to focus on his acting career.

In an open letter on his website Justintimberlake.com, he wrote: ''The last time I wrote you an open letter, it was in January and I promised that it would be a 'Big 2013.'

''Since then, from The Grammys to the release of the first part of 'The 20/20 Experience' to the crowd's response at the VMAs, it's been a wild ride.

''I hope you've enjoyed it as much as I have ... This letter is to tell you that we're not done .. .Not even close.''

Justin's track 'Mirrors' picked up gongs for Video of the Year and Best Editing, while 'Suit & Tie' - his collaboration with Jay Z - took home the award for Best Direction.

The 'Cry Me A River' hitmaker - who reunited with his former *NSYNC band mates at the event - also said he ''can't wait'' for fans to hear his upcoming new record.

He continued: ''On Sept 30th, the second half of 'The 20/20 Experience', 'The 20/20 Experience 2 of 2', comes out.

''Since all these songs were written together over a year ago, it's been so hard to wait this long to release them. I can't wait for all of you to hear The 20/20 Experience in full.''
