Michelle Williams is mourning the loss of her beloved father.
The Destiny's Child star broke the sad news to her Instagram followers as she shared her heartache at the death of family patriarch Dennis Williams, who was just 68.
In a lengthy caption paying tribute, Michelle indicated he had battled a long-term illness, but did not add any further details.
"I just don't know what to say or where to start," she began. "Daddy, you fought harder than those of us that are in good health. For 15 years, you FOUGHT!!! You truly outlived moments where we thought you wouldn't make it!
"Mommy said last night she sang songs to you and you looked so content and had a look of peace in your eyes. You weren't in any pain either!! The Lord took you in his arms this morning and I'm so thankful that you are resting in Him!!! I love you Daddy!!!!"
The singer was inundated with messages of condolence from her fans and famous friends, including Tamar Braxton, Jermaine Dupri, and Tina Knowles-Lawson, the mother of her Destiny's Child bandmate Beyonce.
"My Belle, I am so sorry !!! Your dad was a true warrior...," Tina wrote. "we love you so much."
She also called on her own Instagram followers to keep Michelle and her loved ones in their thoughts during the tough time.
In a post on Monday, Tina shared: "Please Prayers up for Michelle @michellewilliams and her beautiful family who lost their Patriarch Mr. Williams yesterday".
