Newlywed singer Ciara has sparked rumors she is pregnant with her second child after stepping out in an unusually loose-fitting outfit.

The Goodies star is well known for showing off her toned figure in tight clothing, so when she attended a party at New York City's Refinery Hotel on Tuesday (18Oct16), to celebrate her new role as brand ambassador for Revlon cosmetics, fans began questioning her baggy wardrobe choice.

The all-white satin ensemble featured a tuxedo jacket and pants, which completely hid her waistline. She also chose to pin the top button hole in her jacket, instead of properly fastening it, allowing the piece to hang loosely around her midsection.

The 30-year-old opted for a slightly more fitted outfit on Wednesday (19Oct16), when she served as a guest co-host on morning show Live! With Kelly. For the TV appearance, she teamed black wide-leg pants with a matching one-shouldered Peplum top, which again covered her stomach area.

Ciara, who wed footballer Russell Wilson in July (16), has yet to comment on the speculation, but E! News sources suggest the rumors are true.

"Ciara is pregnant and is so excited to be a mom (again)," says one insider. "Russell would like to have two to three children. They both would like a big family."

The singer employed similar fashion tactics three years ago, when she fell pregnant with her son Future Zahir with her ex-fiance, rapper Future. She only confirmed her baby news three months later, in January, 2014.

At the time, she admitted, "I kind of want to take the theme that 'baggy is the new sexy'. I don't know, I just want to be comfortable. When I can't wear heels anymore, I won't wear heels. I'll be putting on my Jordans (sneakers). My Jordans and my Uggs (sheepskin boots) will be my best friends, but it's all about being comfortable."

The unconfirmed news emerges three months after Seattle Seahawks quarterback Russell insisted he and his new wife, who had famously abstained from sex before marriage, were not in a rush to expand their family.

"Down the road, I would obviously (want kids)," he told E! News in July (16). "She does too and hopefully, God willing, as long as they're healthy, that's what we pray for and whether it's a boy or girl, who knows but we've got some time for that... She's making her music right now and I'm playing my sports and hosting shows so we're pretty busy."
