The insider also explained why Lopez was so eager to walk down the aisle to marry Affleck, as quickly as she could.
"[Lopez] has been ready to get married since the night that Ben proposed. She wanted to lock this down and remove any chance for cold feet ASAP!"
As we know, the Marry Me star and The Man With The Phoenix Back Tattoo were first set to wed 20 years ago, one day before the ceremony. But despite calling off the wedding in 2004, the pair reconciled in 2021 to take another go at their relationship.
Despite being on a solo trip to Lake Tahoe, Garner was still very supportive of her ex-husband's relationship with Lopez.
Back in April, a source spoke to E! News about whether she was upset or not about Affleck and Lopez getting engaged.
"Ben told Jen and the kids, so they knew about it," a source close to Garner informed the outlet, adding that, "Jen is happy for Ben and knows that J.Lo has been a positive influence in certain ways".
And in late March, a source close to Garner told Entertainment Tonight that she and Affleck have a better relationship than the public might think, adding that she has always been "supportive" of the new couple.
"Jen Garner and Ben get along well. She is understanding and supportive of Jen and Ben’s relationship," the source said.
"She knows Ben is doing well all around and at the end of the day, she just wants what’s best for the kids and for things to be seamless and unproblematic. She wants everyone to be happy and healthy and her kids are always the priority. Everyone is feeling good at this point and looking forward to the future."
No matter what, our Jenna Rink deserves nothing less than peace and happiness.
