The verified account, which is managed by Legacy Recordings, was actually created last week -- posting its first photo on Oct. 21 -- but picked up steam after the Destiny's Child Twitter account pointed to the new Instagram on Thursday.
Destiny's Child first formed in 1997 with Beyoncé Knowles, Kelly Rowland, LaTavia Roberson and LeToya Luckett -- who previously performed together under the name Girl's Tyme. The group went on to release several No. 1 singles, including "Bills, Bills, Bills" and "Say My Name," before Luckett and Roberson left the group and were replaced by Michelle Williams and Farrah Franklin. Franklin made her exit in 2000, leaving the group as they're best known: the trio of Beyoncé, Rowland and Williams.
The trio continued to release hit after hit -- including "Bootylicious" and "Survivor" -- over the course of the next few years, before disbanding in 2006.
With the newly released Instagram, fans have understandably lost their minds, with many speculating that the group may be reuniting for its upcoming 20th anniversary.
The band briefly reunited for Beyoncé's Super Bowl XLVII halftime show in 2013, performing "Bootylicious and "Independent Women," and then again in 2015 at the 30th Annual Stellar Gospel Musical Awards.
"Sometimes you just know when to show up," Williams told ET in 2015 of the trio's performance. "Last year they came on my song 'Say Yes' on my album Journey to Freedom. Then they agreed to do the video and I was like, 'We need to just do it one time together because it's one of their favorite songs.' It's so easy to just pick up the phone and say, 'Ya'll want to do it? Yes? Cool!'"
"Friendship is the foundation of everything we do -- no drama," she added. "People are looking for drama but we have none to give you. It's literally friendship and sisterhood and respect."
