Ciara is one very yummy mummy and she's definitely not shy about it. The chart topper has once again showed off her post-baby body in a low-cut bathing suit during swimming lessons with her 6-month-old son, Future.

In an Instagram post that she shared with her fans on Tuesday, Ciara can be seen seductively posing for the camera with no makeup on in one pic. In another shot, the single celebrity mom can be seen cradling her son in the pool, captioning the pic with, "#Usie."

Many of her followers seemed to be alarmed by her son's appearance, commenting with, "Don't feed him that much he looks like a Japanese sumo warrior. He's soooo chubby!" along with, "He's big but he's beautiful. He's only 6 months!"

Meanwhile, there's new speculation that Ciara might have full custody of their child, as the rapper has not been seen with the small tot for several months now.

While Ciara has been posting photos of her and baby Future on her Instagram account on almost a daily basis, it seems as though Future, who already has several children with multiple women, has been mostly concentrating on his music career, according to his social networking accounts. There is also a good chance that Future might simply not be posting photos of the moments he spends with his son as well.

Ciara has never specified who has primary custody of their child, who was born in May earlier this year, although fans are speculating that the baby lives mostly with her.

Future has so far not made any public comments about his son or Ciara since the couple broke off their engagement last summer.
