It wasn't Thursday but apparently Justin Bieber wanted a little throwback song singing one of the greatest hits of the famous Boyz II Men's 'I'll Make Love To You' last Sunday at the W Hollywood's Weekly Jazz Night event on the rooftop.

It was indeed a Jazz night as Bieber sang his own rendition of the hit song complete with a Jazz band and of course, hundreds of people screaming. Bieber was looking very Jazzy in his fedora hat and his usual sweater and baggy pants attire that night.

It seemed like the original singers were quite impressed with the young Bieber after seeing the videos posted by Bieber himself on his Instagram writing, "A little jazz night," as caption.

When Boyz II Men apparently saw the series of clips and how well Bieber sang their hit song, the singing group took to their social media their applause for the singer. "@justinbieber thanks for singing our songs #IllMakeLoveToYou! Next time you're in #Vegas join us @TheMirageLV," the group wrote on their Twitter account.

The post even sparked rumors of a possible joint concert of Bieber and the group. Although it is still unconfirmed, it is however still possible as there are already the desire coming from Boyz II Men to perform with Bieber on stage.

Fans, both of Bieber and Boyz II Men are now quite anxious if there will indeed be some collaboration between the two as it will make a phenomenal combination with Bieber bringing in some fresh flavour for the classic RnB style that Boyz II Men offers.

After Bieber's performance, it has been reported that he went straight to dancing and partying with his pals Stanaj, Nikki Leonti & The Honest Cheaters and Brooke Lynn's Burlesque. Bieber stayed at the venue from 11:30 pm until closing, reports suggested.
