Jennifer Garner and Ben Affleck are currently living together, but are they also expecting a child?

On Thursday, when Garner was spotted arriving to Los Angeles from Europe with her daughter, photographers noted that she appeared to be keeping her tummy concealed.

"Jennifer Garner keeps her tummy concealed amid reports she's pregnant with her fourth child," X17 Online reported on Friday, noting that Garner could be hiding a baby bump.

While Garner and Affleck have been separated for one year, they remain close, which has led to swirling allegations regarding the possiblity of them getting back together.

"They will continue to live in the house together and have no plans to change that arrangement," a source told E! News in March. "They are in a really good place right now. A lot of the dust has settled and they have become accustomed to their new life, which is separate but together in a lot of ways. They continue to make the family their first priority and they have always been on the same page about that."

Earlier this year, Affleck opened up about his former partner and their relationship in a candid interview.

"I am a giant fan of Jennifer," Affleck recently said on CBS This Morning, via E! News. "She's just a fabulous person. She's just a wonderful person. She's a great mother. She's a real talent."

That said, Affleck acknowledged that things between him and Garner aren't exactly the way he expected they would turn out.

"Life doesn't always turn out exactly the way you want," he continued. "We're doing our very best and we're putting our kids first and that's how we're focusing on our day to day lives and we don't know what the future's gonna hold, but each step that we take is one where we prioritize our children and everything else comes second. And she's just so good at doing that and has set such a good example and a lead that I follow. She's somebody that I admire and respect and remain excellent friends with."
