Hollywood couple Jennifer Garner and husband Ben Affleck came uninvited in a kid's birthday party the past weekend in Detroit.

As the couple search for some place for their brood to hang out, it turns out that they have actually crashed into someone's party. According to the recent news, the couple actually finding some place for their two year-old son, Samuel to play while they stopped by Detroit Kid City. The couple was in town since the actor is there as he films his upcoming movie, "Batman vs. Superman: Dawn of Justice" and now that they're in search, it has been revealed that the venue was closed for a party.

Instead of going somewhere else, the couple tried to ask if they could stick around for their little child to play. Well, who could resist the superstar family? It is definitely one of the most memorable experiences for an ordinary person to spend some time with one of the Hollywood's famous celeb couples.

Reports also said that the couple has been warmly welcomed in the Superman-themed birthday party. Ben Affleck and Jennifer Garner's presence would be quite ironic as the actor plays the new Batman in his film, but with the delight of the Hollywood actor being in the said birthday party, the birthday boy has been eager to meet the new Batman actor.

"I spoke with Ben for 10 or 15 minutes and he was very pleased with the facility. He was very interested in getting a Detroit Kid City out in LA," Garrett Dixon of Detroit Kid City told the Detroit Free Press. "He said they had a blast and will definitely be in contact with us."

The couple reportedly spends some time together while the actor is filming in Detroit as they also become excited for the upcoming film. Ben Affleck and Jennifer Garner just recently celebrated their wedding anniversary in a low-key date.
