AceShowbiz - Is Ciara having a bun in the oven? That is what fans have been speculating about after she attended the taping of VH1's "Dear Mama: A Love Letter to Mom" tribute special on Sunday night, May 5. While the songstress looked as stunning as always, fans couldn't help but wonder whether she was trying to hide her baby bump with her outfit.

For the event, Ciara opted for a gold mini jumpsuit that she paired with a pair of matching heels and clutch. The outfit featured ruffles that covered her belly, prompting fans to think that the "Level Up" singer might be hiding her baby bump. "Sis pregnant," one convinced fan said underneath photos from the event that she shared on Instagram.

"Is that a baby bump," another wondered, while one other said, "That beautiful Baby #3 in the oven, Congratulations!" Someone else echoed, "Baby no. 3 on the way," as one individual urged Ciara to "announce your pregnancy." Some others, meanwhile, were focusing on her beauty rather than her stomach, writing similar comments such as, "Beautiful," "Gorgeous" and "Stunning."

Ciara has yet to respond to the speculation.

Her pregnancy speculation aside, Ciara was all smiles at the event as she was joined by both her mother and grandmother. Sharing her favorite moments with her mom when asked by reporters on the red carpet, she said, "Sharing with my mom that I'm having a baby! That's pretty sweet. She was in shock. And it's beautiful, and now I have two babies, and the shock never gets old for my mom. It's a sweet thing to be able to share with your mother and my mom was really proud and excited that she [was] going to be a grandma for the first and second time!"

Ciara is a mother to Future Zahir Wilburn, her child with ex-fiance Future, as well as Sienna Princess Wilson, whom she shares with husband Russell Wilson.
