Try not to cry or anything but err.. that\'s it, it\'s all over. One Direction\'s American On the Road Again tour is officially done and dusted, as the boys performed their last show of the leg in Boston on Saturday night.

As well as being a big finale, it just so happened to be Niall\'s 22nd birthday too, but as well as serenading him with HBD before he jetted off to celebrate in Vegas, what other magical moments did the boys have in store for their last US crowd pre-hiatus?

If you\'re not already sailing away in a rubber dingy on a river of your own tears, then here\'s all the best bits from the OTRA Boston show. You\'re not ready for the 4/4 group hug at the end.

So there was this little dance to the camera from Harry, which we need the footage of as a matter of life or death.

This absolute corker of a fan project taking over the entire stadium with signs which read \'Happy Birthday Niall, Boston loves you\'. You GUYS.

The extremely successful fan project tonight for Niall\'s birthday! Great job #OTRABoston it looks amazing! 9-12-15 pic.twitter.com/bbHc33xK29

Liam revealing that they\'re way ahead of us and have already recorded the next music video, confirming that we literally can\'t keep up anymore.

This fan sign, which must surely be one of the greatest banners that\'s ever graced a One Direction concert.

I\'m standing in line & @louisdomlinson has the best sign!!! 😍😂

Niall being absolutely baffled af by this fan sign of his face stuck to a giant piece of bread. Can someone explain this to us please.

Harry basically being an embarrassing dad to Sandy and telling everyone about his upcoming wedding to a "real life woman".

The never-ending battle of Liam vs Louis still raging on thanks to Tommo and his constant supply of silly string.

A bit of shameless flirting between Harreh and this lucky lady in the crowd.

This truly magical photo of the birthday boy, thanks to Liam James Payne and his understanding of what we all want in life.

And last but not least, this wonderful group hug to mark the end of another era. Don\'t touch us.

AGH, this is all happening so fast. We\'re not ready for it to be nearly over.

What was your favourite moment from OTRA in Boston? Is that officially the cutest One Direction group hug there ever was? Let us know with a tweet to @Sugarscape.
