Tackling powerful ballads by a superstar known worldwide as "the voice" is no easy feat.
Many have come before her and tried, but Netherlands native Glennis Grace, 38, could be the best Whitney Houston impersonator yet.
Videos of Grace belting out Houston's tracks including I Will Always Love You, Greatest Love of All and Didn't We Almost Have it All have attracted hundreds of comments on social media about how the Amsterdam native "sounds exactly like" the late superstar, who died at the age of 48 in February 2012.
But it wasn't until Grace's rendition of Houston's Run to You - performed at the 2017 Ladies of Soul concert at the Ziggo Dome in Amsterdam last week - that her work started to go viral.
