"Last time you were here was three years ago," Jimmy Fallon reminds Ali, "and you were pregnant on the show."

"Yeah, I came on, and I was pregnant, and it went so well," Ali beams. "So, I told my husband I was going on Fallon so I gotta get pregnant!" She then stands up, opens her blazer and shows off her visibly pregnant belly.

"I've been trying to hide it as much as I can," she says. "I was still shooting my spy drama [Legends]—so I have to be, like, a covert spy in my real life, too. I'm wearing blazers and push up bras and everything you can do to distract because the bump is growing."

Ali and Hayes got married in 2009 and welcomed their first son, Theodore ("Teddy"), in 2010.

“We’ve told him about it, and I actually will say, ‘Teddy, wait, [pause...pause] it’s talking to you,’ and he’ll be, ‘What, Mom, what’s going on?’ And I go, ‘It says that it loves Batman and was wondering if it can watch it with you?’ He goes, ‘Oh my God, Mom! Batman, I can’t even watch it! Mom, can I watch it with the baby?’"

"He's getting ingratiated to it." She laughs. "We're getting him ready to break all the rules."

In the meantime, Ali has a new cookbook out with all her fave recipes—and pics of cute Teddy in the book, which she shows in the segment. She also talks about Teddy's penchant for knives...! Check it out here:
