Dropping her highly anticipated album Anti [1] out of the blue apparently wasn't enough for Rihanna [2], because the singer decided to continue to blow minds (and ears) this month when she did a surprise karaoke performance of "My Girl" with Miguel at his invite-only art installation at LA's Summit Motel [3] on Saturday night. After teaming up with the "Coffee" singer on The Temptations' classic, Rihanna also treated everyone to a soulful rendition of Mary J. Blige's "Not Gon' Cry," which, coincidentally, almost brought a tear to our eye. Check out both moments, then listen to Rihanna's latest collaboration with Drake on her bangin' new single, "Work." [4]
