Jimmy Fallon is returning to The Tonight Show Monday after taking a week off to mourn the passing of his "biggest fan," his mother Gloria.
Questlove, the frontman for The Tonight Show's band The Roots, wants Fallon to know he has his back.
"We’re in show business. And the show must go on," Questlove told USA TODAY at Saturday's Governors Awards. "Where he leads, we’ll follow."
Gloria Fallon died Nov. 4 with Fallon at her side at the hospital. "Today I lost my biggest fan," he wrote in a statement.
Questlove said he's been in frequent contact with Fallon since his loss.
"This is beyond, 'My heart and prayers are with him.' We’re family now, he’s my brother. So it’s a loss," said Questlove. "She was everyone’s mom on that set.
"Jimmy is a strong person," Questlove added. "To mourn and to remember is important."
Questlove says Fallon was there for him when his father, musician Lee Andrews died in 2016.
"(Fallon) was my rock," said Questlove. "We’re there for each other."
Fallon's guests Monday are Jeff Daniels and Mary J. Blige.
