The choice of Lopez to headline the performance - which saw her singing a medley of the label's classics like "Dancing in the Street", "Please Mr. Postman" and "Do You Love Me" - has been a source of controversy since it was first announced and again on Sunday after it finally aired. Lopez's performance did little to smooth things over with these viewers.
Some online questioned why a black artist wasn't chosen instead of Lopez, but she received support from Smokey Robinson, who joined her in a duet to perform "My Girl", a song he co-wrote. Motown was a black-owned record label that put out music by predominantly black artists like the Supremes, the Temptations, Stevie Wonder, and Marvin Gaye.
Lopez also opened up about her performance on the Grammy red carpet, telling Ryan Seacrest that she wanted to dedicate the performance to her mother.
She added: "I grew up with this music and me and my sisters, the three of us, we were, like, the backups".
Jennifer Lopez turned the Motown tribute into the J-Lo show. You can't tell people what they can and can't do, what they should sing or not sing.
The "Love Don't Cost A Thing" singer detailed how Motown's founder, Berry Gordon, was "thrilled" about her involvement. "You gotta do what's in your heart".
"They [Grammy producers] know how much I have been influenced by that music, and so it was a natural fit for them", the "Second Act" star shared. "But for some people, [it wasn't], and that's OK".
