In an Instagram video, Destiny Child's singer Michelle Williams shared a letter she received from a fan who apparently meant to send it to the other Michelle Williams -- aka the Oscar-nominated actress.

Michelle Williams welcomes fan mail, but when fans say her name, say her name, they aren't always referring to the former Destiny's Child singer. Williams, 45, took some time to answer letters from fans as she's in New York City starring on Broadway in Death Becomes Her.

The admirer lauded the Destiny’s Child vocalist for her performances in movies like Blue Valentine, Manchester by the Sea, and The Greatest Showman, and Williams described the note as “absolutely phenomenal.

So, there's Michelle Williams, the Grammy-winning former member of Destiny's Child who's currently starring on Broadway in Death Becomes Her, and then there's Michelle Williams, the Oscar-nominated actress from movies such as The Greatest Showman and Brokeback Mountain.

Michelle Williams reacts to a fan mistaking her for the other Michelle Williams and asking her to sign photos of the 'Dawson's Creek' actress. The singer sharing a video of the mix-up on Instagram, while in her dressing room for 'Death Becomes Her' on Broadway.
