AceShowbiz - Jennifer Garner and John Miller's rekindled romance appears to be a real deal, especially now that they're spending time together with their kids. It was unveiled that the pair's respective children met each other at the "Juno" actress' 50th birthday celebration.

"John's kids finally met Jen's kids," a source told Us Weekly, adding that they celebrated Jennifer's latest milestone with a food drive on Saturday, April 16. The insider continued, "Lots of kids and family were invited, including John's kids, his parents, his brother and his [brother's] wife."

"They all had friends there," the unnamed informant went on noting. "It was casual and easy."

Jennifer shares three kids with her ex-husband Ben Affleck, two daughters 16-year-old Violet and 13-year-old Serafina, and 10-year-old son Samuel. As for John, he shares two children with his former wife, Caroline Campbell.

Jennifer and John were first linked romantically in 2018, just shortly after the "Peppermint" star finalized her divorce from Ben. The pair, however, decided to go separate ways after two years of dating. "He was ready for marriage and she just couldn't commit. They parted on very amicable terms," a source told Us Weekly in August 2020.

The "Alias" alum and the CEO and Chairman of Cali Group sparked reconciliation rumors in May last year. "Jen and John are back on," an insider told the outlet. The so-called inside source went on to spill, "It started up a few weeks ago."

Later in August, the alleged on-again couple was photographed together outside an apartment building in New York City. They didn't show any PDA as Jen walked a few steps ahead of her rumored boyfriend while they seemingly headed into an entrance.

While Jennifer is seemingly getting more smitten with John, her ex-husband Ben reached a new milestone in his relationship with Jennifer Lopez. The "Batman v Superman: Dawn of Justice" actor and the pop star got engaged for the second time earlier this month after rekindling their romance last year.
