Amid spreading rumors about Jennifer Garner and Ben Affleck's reconciliation, the ex-couple was spotted together enjoying a family dinner in London along with their three children — Violet, 10, Seraphina, 7, and Samuel, 4. According to the Daily Mail, Affleck joined Garner and his kids after wrapping up shooting for the latest Batman installment, "Justice League: Part One."

Affleck reportedly forgot to remove his makeup and walked through the streets with eyeliner, a face full of foundation and matte powder. Garner appeared completely make-up free for their outing, Daily Mail reported.

The news comes amid rumors that Affleck gifted Garner an 11-carat diamond as a "pre-11th anniversary" gift.

According to the National Enquirer, Affleck “hand-delivered a massive, super sparkly ‘pre-11th anniversary’ diamond to Jen, but not set in a ring.”

"Not-so-subtly popping his ‘new vows’ question, Ben presented Jen with a whopping 11-carat diamond, one carat for each year since their marriage. They’d split just a day short of their 10th anniversary last June amid allegations of his nanny cheating," a source told the tabloid. “But not wanting to scare Jen off with an actual ring, Ben had the huge stone set into a gorgeous platinum necklace and told her to consider it a ‘promise trinket’ for his heartfelt intentions, and hopes she’ll suggest resetting the rock into a new wedding ring.”

However, Gossip Cop reported that the National Enquirer report was false.

Rumors about the couple's reconciliation also come amid several reports stating that Garner is pregnant with Affleck's fourth child.

Garner and Affleck announced last year they will end their 10-year marriage but did not reveal a specific reason behind the split. Following the announcement, the couple was surrounded with several cheating rumors.
