On Sunday, Contact Music pointed out how Affleck's ex Jennifer Lopez had discussed her previous relationship with the Gone Girl star- and apparently, this did not make Garner happy at all.

"She's absolutely p---ed that J Lo has been discussing her relationship with Ben," a source reportedly told Life & Style. "Jen's livid that in almost every interview, she brings up how Ben was her first true love."

If this is true, then the actress is supposedly upset for the sake of her three children that she shares with Affleck.

"Jen thinks it's so disrespectful of J Lo, especially because she and Ben have three kids and it's hurtful to them, too!" the source said.

Lopez wrote about her romance with Affleck in her book "True Love" where she gave emotional details on how hard this breakup was for her.

"I had breakups and things but I'd never felt heartbroken until we called off that wedding," she said. "It was devastating to me, maybe because it was so public."

The singer gave the impression that she really thought it was going to work out between them.

"I really felt like I had found somebody great and he had found somebody great and we thought we could make it work," Lopez said.
