If Madison Beer has not done so already, she might want to call Justin Bieber to say thank you, maybe.

The pop star has just deemed 13-year-old Beer the next big thing, bestowing on her the same golden touch Twitter endorsement that made Carly Rae Jepsen and her " Call Me Maybe" single a breakout success.

Bieber tweeted an endorsement of Beer to his 25 million Twitter followers Tuesday and posted a YouTube video of her singing Etta James' "At Last" to his Twitter page:

"wow. 13 years old! she can sing. great job. #futurestar- http://youtu.be/_0otR5cFhew," he wrote.

Those nine words from the Biebs made Beer a worldwide trending topic on Twitter in less than 24 hours and increased views of her videos on YouTube by more than 60,000 and counting.

The previously unknown Beer's response?

" @justinbieber OMGOGMFHAHDBSBAWHEBSBSHHWEHHDXHSHHAFBBAGEEHYBT I CANT BELIEVE THIS IS HAPPENING. I AM CRYING," she wrote to her now nearly 20,000 Twitter followers.

Bieber didn't leave his endorsement at just that. He later posted a video of Beer, a New York native, doing a mash-up of Jensen's hit and his own "Boyfriend" single to Jepsen and sent her mash-up of a Bruno Mars song to the singer himself.

"haha. @carlyraejepsen watch this. pretty funny. reminds me of my old videos. #MashUpFReakOUT youtu.be/yYt7DfLHwPM," Justin wrote and then tweeted again, "this is just how i started. i love it. @brunomars u gotta see one. She is great. #STAR- youtu.be/COhrE0aW_tk"

Beer is reportedly in talks to sign with Scooter Braun, the talent manager who discovered Bieber on YouTube and who also now represents Jepsen.

Jepsen, 26, was a Canadian singer known only from her appearance on the Canadian version of "American Idol" when Bieber signed her to his record label and began to spread the word to his fans about her music.

After Bieber tweeted about her song, "Call Me Maybe," in February, calling it "possibly the catchiest song I've ever heard," it became a megahit. The song has been No. 1 on Billboard's Hot 100 chart for the past five weeks, and earned parodies from the likes of Bieber's girlfriend, Selena Gomez, the Harvard baseball team, James Franco and even the Cookie Monster.
