The singer was reportedly seen walking around and speaking on her cell phone, but was clutching her chest and shoulder.
However, a source tells People that Ciara is "fine."
Adds an L.A.P.D. spokesman to the mag, "From what we can gather, it was exchange information only."
Ciara's husband, NFL star Russell Wilson, also said his wife was fine
"Momma Wilson & Baby Wilson are feeling great! God is good! 🙏🏾😇😍👼🏽," he tweeted.
She is reported to be in her third trimester.
Photos from the scene show both police and paramedics on the scene. One image, posted to TMZ, shows her being assisted as she exited her vehicle.
"Blue is one of my favorite colors..," she wrote alongside a photo of herself wearing a blue-and-white striped robe atop her otherwise all-black ensemble.
She already has one son, Future, from her marriage to rapper Future.
Around the time of the crash Russell tweeted about a black and white picture of his wife and stepson. "Love Always Wins. #Family," he wrote.
