Kelly Rowland’s “Motivation” gets an extra push courtesy of R. Kelly. “Baby I’m gon’ be your motivation/ Take you to school, give you a sex education/ Bend it over real quick without hesitation/ I’m gonna get you pregnant, you’ll have the next generation,” sings Kellz on his raunchy remix to Rowland’s hit single, which jumps to No. 1 on the Billboard R&B/Hip-Hop Songs chart this week.
