The iconic singer's final resting place was given a tombstone last week, after being unmarked for more than a year following her death from accidental drowning in February 2012, reported Contactmusic.
The iconic line is inscribed on a new tear drop-shaped monument, which also has a heart shape embossed on it.
The ornate gravestone was installed at the Fairview Cemetery in Westfield, New Jersey, where Houston is buried next to her father.
As well as the lyrics, the towering tribute also heralds the gifted songstress as 'The Voice'.
'I Will Always Love You' was first written and performed by country singer Dolly Parton but became synonymous with Houston after she recorded it for the soundtrack of her 1992 movie, 'The Bodyguard'.
Houston's version earned her two Grammy Awards and has sold over 12 million copies around the world.
