Jimmy Fallon ''kinda cried'' when he sent his daughter to her first day of school this week.

The 43-year-old talk show host dropped his five-year-old daughter Winnie off at kindergarten for her first day of school this week, and has admitted both he and his wife Nancy Juvonen were emotional about the prospect of seeing her grow up.

Whilst interviewing Jennifer Garner on his talk show 'The Tonight Show starring Jimmy Fallon' - which was aired on Wednesday (05.09.18) - he said: ''She just went to kindergarten today. I didn't cry. But I did, kinda. I kinda held it in - I didn't want to be the dad that cries.''

To which Jennifer - who has three children, Violet, 12, Seraphina, nine, and Samuel, six, with Ben Affleck - asked: ''Did she skip in or did you see her trying to be brave? 'Cause that's what I can't handle.''

Jimmy - who also has three-year-old daughter Frances with his spouse - then admitted that whilst his wife ''totally lost it'', he was made to act ''cool'' in front of the other parents.

He said: ''Just walking to the school made me start getting sad. I was like, 'I'm not gonna [cry].' My wife totally lost it. She was crying and she got all the other moms crying. The other dads were cool, so I had to be cool.

''[The other parents are] like, 'Are you okay?' I'm like, 'Everything's fine! Have fun, Winnie, have fun at kindergarten! I gotta get out of here!' I couldn't hide it at all, it was absolutely terrible.''

Meanwhile, Jimmy recently said he was determined to make sure his daughters learn to play outside, rather than becoming dependent on electronic devices.

He said: ''I really want them to play outside more than anything because that's what I did with my sister when I grew up. No iPads, no iPhones. Get dirty, go on the swings and just play and play and play until you're exhausted.''
