Megan Fox offered to get co-star Will Arnett's girlfriends snacks because they seemed so young to her.

The Transformers actress starred alongside the Arrested Development comedian in Teenage Mutant Ninja Turtles in 2014, while he was dating following his separation from Amy Poehler in 2012. And Megan has reveals that the actor went through a series of girlfriends during filming, most of whom she met on the set.

"He was sort of dating a lot and every other week there was a new girlfriend and he would bring them to set," she explained to chat show host Conan O'Brien. "They were progressively getting younger and younger as the weeks went on, and it got to the point where I was like, 'Buddy, I'm worried. Should I talk to craft service and make sure they have Lunchables (children snack kit) for your girlfriend?...There's no food here with cartoon characters on it.'"

Before she told the story, she joked to Conan that Will "doesn't appreciate" her telling the anecdote and that he "doesn't want me to talk about it", but that didn't stop her exposing him. She added afterward that he didn't like her cracking the Lunchables joke.

Will and Amy filed for divorce in 2014, and he has since been linked to celebrity chef Katie Lee, actress Arielle Vandenberg and producer Erin David. Amy, who has two sons Archibald, seven, and Abel, five, with Will, dated comedian Nick Kroll for two years until they split last year (15).

Megan, 30, reunited with Will, 46, on sequel Teenage Mutant Ninja Turtles: Out of the Shadows, and when they promoted the movie together in April (16), she surprised onlookers with a baby bump. She joked online that Will and her previous co-stars weren't the father.

She is expecting her third child with estranged husband Brian Austin Green, who she filed for divorce from in August (15). Their divorce is reportedly on hold as it appears they have rekindled their relationship.
