Ciara is now back in the studio, following her split from rapper fiancé Future and impressive 60-pound post-pregnancy weight loss.

After giving birth to baby boy Future Zahir Wilburn in May, the R&B star recently took to her Instagram account to share a couple of photos showing off her toned post-baby ab. One of the images sees her lying down on a bed, sporting black underwear and bra by Calvin Klein. "I feel so proud to say that 4 months after delivering a 9 lbs. 10 oz. baby, I can finally rock My Calvin's! #mycalvins," she wrote the following caption.

CiCi then captioned another snapshot of herself in a gray CK undergarment set: "After Delivering My Son I Feel Like There's Nothing I Can't Do. I Feel Like I Can Conquer The World. #ANewMe #NewMusic. So Proud To Rock #mycalvins 60lbs later!!"

Just a few days after teasing fans with the hashtag "#NewMusic," the "One, Two Step" singer revealed on Instagram that she is now working presumably on the follow-up to her 2013 self-titled album. She posted a picture taken with producer Polow da Don, who worked on her R&B hit "Promise" back in 2006.


Polow da Don previously teamed up with other recording artists, including Kelly Rowland, Robin Thicke, Kelis, Jennifer Hudson, Nelly, Christina Aguilera and most recently, Nicki Minaj on her platinum single "Anaconda." Her sixth studio album is set to feature works from Mike WiLL Made-It and highly acclaimed hitmaker Dr. Luke, who also produced Katy Perry's "Dark Horse."

Meanwhile, Ciara is said to have taken Future back for the sake of their son after calling off their engagement last month over infidelity. "Ciara knows he cheated and she hasn't truly forgiven him for that," a source revealed to Hollywood Life. "But she doesn't want to be selfish to her boy and doesn't really want her boy to grow up without a father."

"Even though she knows Future is an a**hole, she does think it would be in her boy's best interest to grow up with him in his life," the source added. "She's looking at it from the perspective that Future is a rapper whose career is on fire and exploding daily."
