Justin Timberlake: #hashtags with Fallon, concert with Kimmel

Justin Timberlake and Jimmy Fallon know just how #ridiculous the hashtag frenzy has become.

Timberlake, 32, who’s all over the media this week promoting the next installment of his album “The 20/20 Experience: 2 of 2,� out Monday, appeared in a pre-recorded segment for “Late Night� on Tuesday just to have a little hashtag conversation about what he and his “History of Rap� collaborator have been up to. The kicker? They utilized the overwrought social media colloquialism in an everyday verbal repartee.

The pair talked about everything -- #chillin #working #homemade #oatmealraisin cookies #cookiemonster #lololololololololololololol #orangeisthenewblack #barney #dinosaurs #iceage #rayromano #halloween #lifedecisions #monalisa #ninjaturtles #dentalcare #wecantstop and #shutthe...up. That last one came courtesy of Fallon’s “Late Night� band leader Questlove and is exactly how we feel when we see nonsensical paragraph-long hashtags.

So, thank you boys. Consider this a public service announcement and a demonstration of the proper way to finger-mimic the hashtag in conversation. (Watch the #banter in the video above).

Timberlake, who released his latest single “TKO� on Friday, also braved illness earlier in the evening to perform a six-song set for “Jimmy Kimmel Live!� Kimmel’s free two-day concerts also featured Paul McCartney on Monday and shut down a stretch of Los Angeles’ Hollywood Boulevard through Wednesday morning, L.A. Now reported.

“I’m gonna need your help tonight,� the singer told the outdoor concertgoers before he sang “Mirrors.� “If I’ma do this, I need to hear everyone singing. I don’t want to see you big-time me. I know this is Hollywood.�

The ‘N Sync alum took a nearly seven-year hiatus before releasing any new music on his own. The second part of his comeback album comes after the March release of the first part; the 11-track sequel is currently being streamed on iTunes about a week before its official release.

He has also announced that he’ll be launching a world tour to promote the album, with the North American leg starting at the Bell Centre in Montreal, Canada, on Oct. 31. “The 20/20 Experience World Tour� follows his summer stadium tour co-headlining with rapper Jay Z, “Legends of Summer.�
