Just a day after it was revealed Megan Fox was pregnant with her third child, she posted an epic Instagram confirming who wasn't the father.
The pic was a collage that included pics of Will Arnett, Shia LaBeouf and New Girl star Jake Johnson with the caption "#NotTheFather."
"It was pretty humorous," Arnett told me yesterday while promoting his and Fox's new movie Teenage Mutant Ninja Turtles: Out of the Shadows. "I got asked about it about a million times and I had so many great answers that I'm not allowed to say."
He whispered one NSFW joke he wanted to so badly crack. "There's no way because it would instantly be retweeted a hundred million times," Arnett explained. "It's super rude and uncool—but it was great."
So has Arnett bought a gift for the third-time mommy-to-be?
"She is hippy-dippy. I should buy her Birkenstocks or something or a birthing tub," Arnett said. "That's what I'm going to get her. It's like a whole tub and they get in it and everyone's in it at the same time...Chanting and all the fluid is happening at once."
As for TMNT, Arnett said, "It's super fun [and] by far the best Ninja Turtles movie ever made. I'm happy I get to make it because my kids will see it. It's not something they have to wait until they're like in recovery to watch and for me that's like a plus. I'm psyched. "
Teenage Mutant Ninja Turtles: Out of the Shadows is in theaters on June 2.
