Over the weekend, the Baby singer debuted a newer, undercut hairstyle, shaved much shorter on the sides and leaving the top longer and swept to the side, reminiscent of RiRi's look in 2009.
His new look reminded many of JB's once signature, old-school hair flip, showing off the updated 'do at a fan meet and greet in Germany on Friday and leaving his fans swooning on Twitter.
@BieberTheLucky tweeted: "So Justin bieber is single, he is writing new music and he got his hair flip back. WELL HELLO 2009."
Other fans couldn't get over how much it recalled his swoop from back in the day (which was immortalized in his 3-D movie) and he cut off back in February 2011, causing frenzy and headlines, much like this time around.

Meanwhile another fan, @_LukeMace declared the teen star the "god of hair" in light of the new look.
But, the online hysteria over the look hardly ended with declarations of his hair godliness. @carlysraerote: "HE SHAVED THE SIDES OF HIS HEAD I AM CRYING SCREAMING HOLLERING I AM IN COMPLETE ECSTACY RIGHT NOW."
