AceShowbiz - Toni Braxton has finally broken her silence, days after her niece Lauren Braxton's passing at 24 years old. Taking to her Instagram page on Wednesday, May 1 to pay tribute, the "Breathe Again" singer expressed her deep grieve through the post.

Toni shared a picture of her with Lauren, who rocked long and purple braids as she wrapped her hands around her aunt's waist. "R.I.P to my amazing niece Lauren 'Lo Lo' Braxton...," the "Braxton Family Values" star captioned it. "I'm still in disbelief and so very heartbroken Love you...always auntie 'Te Te'."

As reported before, Lauren, the daughter of Toni's younger brother Michael Conrad Braxton Jr., passed away on Monday, April 29 in Maryland. The young woman, who was known to friends and family by the nickname Lolo, was found by her friend who was talking with her in the kitchen before she collapsed. The friend claims she went upstairs for just 10 minutes and when she returned to the kitchen, Lauren was on the floor and unresponsive.

Law enforcement responded to a 911 call around noon on Monday. Paramedics performed CPR, but Lauren was pronounced dead at 12:44 P.M.. Her autopsy results have not been released, but her father told TMZ that his daughter died of causes related to a heart condition.

Lauren's aunt Trina Braxton was quick to pay tribute to her niece on social media. Sharing a picture of smiling Lauren, Trina wrote on Instagram, "God sent me another angel! Rest in Heaven Lauren 'LoLo' Braxton." Meanwhile, Trina's elder sister and Toni's younger sister Traci Braxton told TMZ, "LoLo was more than my niece, she was my daughter; and I, my son and husband are truly heartbroken over her passing."

A rep for the Braxton family said in a statement, "We ask that you please respect the Braxton family's privacy in this time of sadness and loss."

Lauren and his father have been featured on the family's reality series "Braxton Family Values", which airs Thursdays at 9 P.M. ET on We TV. She would have turned 25 years old on May 9.
