The heartbroken 35-year-old talent manager - whose clients include Justin Bieber and Usher - took to Instagram on Sunday (20.11.16) to share a touching tribute to the woman he refers to as "Ma".

He wrote: "I don't know where to start. This morning the world lost one of the great ones. There was no one like her. No one. She loved regardless of all the hate she witnessed in her life. She made everyone smile and she gave and gave and gave and never asked for anything but love in return. The world needed people like Ma more than ever right now. I won't ever let her be forgotten. I will keep my promise. Yael and I promise our children will know her. I was so blessed to call myself your grandson. I love you Ma. Thank you. I will miss you so much. I'm afraid to stop typing because I just don't want to admit you are gone. For all the lives touched by this hero you know you are better for it."

But Scooter also revealed there was happiness amidst the tragedy as just three hours after his grandmother died, his brother Adam and wife Tehillah welcomed twins.

He added: "Like I said she was one of the greats...and in only Ma form 3 hours after she left us my brother Adam and his wife Tehillah brought their twins into the world. Classic...Ma always gave us twice as much as we expected. It is fitting. It just seems to make sense. I will miss you Ma. But I won't forget you. Give a kiss to Apu for me. I love you. We love you. I will talk to you soon. I am so thankful for all that you taught me. Goodnight Ma. #thegreatest (sic)."

Scooter and his own wife Yael Cohen welcomed their first child, son Jagger Joseph Braun, into the world in February 2015 and are expecting a second baby together.
