Twitter erupted in ecstatic celebrations as the All Blacks won the Rugby World Cup for the second time in a row, decisively beating the Wallabies 34-17.

And this guy was definitely in the running for biggest fan out, with this priceless reaction:

Sports stars, celebrities and fans alike were quick to take to social media to congratulate the men in black - with plenty of praise for man of the match Dan Carter.

Valerie Adams, Joseph Parker, Cory Jane, Martin Guptill and Neil Wagner were just some of the Kiwi sports stars offering their congratulations online.


"Didn't I say only Hurricane players would score the tries???" wrote Jane.

Meanwhile, New Zealanders were continuing the early-morning party, with Castle St in Dunedin shut off for the Scarfies.

Politicians from both sides of the house were united for one day at least, with Australian Prime Minister Malcolm Turnball congratulating the "worthy world champions".

Aussie star David Pocock demonstrated how to be gracious and humble in defeat, tweeting that the All Blacks "deserved the win tonight" - managing to use the team's name, after the previous mind games from the Wallabies.

Wallabies skipper Stephen Moore also tweeted his congratulations for the All Blacks.

Willie Apiata's contributions to the All Blacks' training sessions were much appreciated by fans.

Some were wondering whether any of the All Blacks were thirsty, following their epic performance - but sadly, Shane Warne was nowhere to be seen. However, David Warner was around to offer some congratulations.

Sonny Bill again proved himself to be a class act, gifting his winners' medal to a child who ran onto the pitch and was tackled by a security guard - an experience the youngster will surely never forget.

Some concern was shown for that poor little girl who was torn between Australia and New Zealand.

However, Jason Gunn encouraged Kiwis to make the most of their bragging rights - and it's safe to say that plenty of All Blacks fans will be picking up the phone today.
