The pair split in August, just three months after Ciara gave birth to their son, Future Zahir Wilburn. They are reconciling for the sake of their son, according to TMZ.com.
Ciara and Future are also back living together, according to insiders.
The couple had been together for over a year prior to their split. Ciara and the hip-hop star, real name Nayvadius Cash, got engaged on her 27th birthday in October 2013.
Infidelity allegedly played a role in their break up.
Ciara told Brides magazine in July that she met Future through her record label. She explained: "I went into the studio strictly to work, but he was very calm and sweet, a gentleman... I knew right away that he was different. Now he's my best friend in the world, my partner."
