Jennifer Garner was accused of being pregnant with Ben Affleck's fourth child on this week's cover of US OK! magazine.

It was an odd claim considering they have been separated for most of this year and officially announced their split this summer, followed by reports the 43-year-old Argo actor was romancing the family nanny Christine Ouzounian.

Then a new picture surfaces. It shows the 43-year-old actress out in LA running errands on October 5, she opted for a loose maternity-style top that gave the illusion of a baby bump during the casual outing.

After multiple reports claimed that Jen and Ben were pregnant with their fourth child, the actress stepped out looking a bit round in the tummy region.

The sighting took place just as it was revealed by Variety that Ben and Jennifer have listed their Pacific Palisades mansion - which was once owned by film producer Brian Grazer - for $45m.

On Wednesday OK! magazine claimed that Garner has started 'dating Affleck again.' The magazine also stated that during their September 21 dinner at Nobu in Malibu, "they looked just like any other couple having dinner. She seemed happy, and he was very attentive to her," a source said.

It was previously reported that, “She called one of her best friends and just broke down,” a source told the magazine. “But no one is sure if she’s confirmed it with a pregnancy test, much less told Ben, because she’s so secretive.”

Intensive therapy sessions have helped, it was claimed. Indeed, the two have been seen visiting a psychologist in LA in recent weeks, an unusual move for a couple that is splitting.

Jennifer Garner and Ben Affleck have been struggling to figure out where to go from here. Yet, they plan on spending a fun Halloween together for the kids.
