Meet Miranda Sing’s mother and uncle. The Office alumna Angela Kinsey and Steve Little (The Grinder) are set to co-star angelakinseySteve_Littleopposite Colleen Ballinger-Evans in the YouTube personality’s eight-episode Netflix half-hour comedy series Haters Back Off, from The Firm. Based on actress-comedian-singer Ballinger-Evans’s most popular character, Miranda Sings, Haters Back Off delves into the oddball family life of Miranda Sings (Ballinger-Evans), an incredibly confident, totally untalented star on the rise who continues to fail upward by the power of her belief that she was born famous, it’s just no one knows it yet. Kinsey will play Miranda’s mother, Bethany; Little will play Miranda’s uncle, Jim. Both characters had been referenced by Miranda on YouTube for years but never seen. The way Bethany dotes on her daughter helps explain Miranda’s peculiar behavior; while Miranda has suggested that she and her uncle have a unique relationship.

Like she did with the series pickup announcement, Colleen Ballinger-Evans unveiled the castings in character on YouTube. She was joined by Kinsey (video above).

Ballinger-Evans developed Haters Back Off with her brother, Chris Ballinger, and Perry Rein & Gigi McCreery through The Firm. The four executive produce with The Firm’s Jeff Kwatinetz and Josh Barry. Rein and McCreery serve as showrunners.
