Jennifer Garner and her estranged husband, Ben Affleck, were spotted in London after they returned from their vacation in Paris with their children, according to the Daily Mail. Garner and Affleck recently reignited reconciliation rumors after they spent quality time together in the French capital amid reports that the "13 Going on 30" star is pregnant.

According to the Daily Mail, Garner and Affleck were pictured walking through St Pancras International with their children after their Paris break. Garner visited London to spent time with Affleck who is filming his next movie "Justice League" in England’s capital. The 44-year-old actress was reportedly seen wearing a white and black outfit teamed with a purple scarf wrapped around her neck, while Affleck looked casual in a leather jacket with a sheep-wool collar.

Last month, rumors surfaced that Garner called off her divorce after learning that she was pregnant with Affleck's fourth child. The rumor was debunked by Gossip Cop. However, several reports speculated that the two are back together after they were spotted kissing while in Paris, according to the Daily Mail. 

According to a Hollywood Life report, Affleck and Garner, who announced their split in June 2015, are still attracted to each other and they have kept their options open.

“Ben and Jen are in a weird place. They have so much history and kids together. They are comfortable with each other and there is still an attraction. Jen knows nobody is perfect, she is just trying to be nonjudgmental,” a source told Hollywood Life. “They have always put the kids first and part of that means working on things between the two of them. They are both taking it one day at a time and trying to stay open-minded about their options."

However, another source told Us Weekly that there is no romance between Affleck and Garner.

“They were acting like a normal family, but I don’t think there was any romance between Ben and Jennifer,” a source told Us Weekly. “They were just acting like great parents. The kids were really happy!”
