Anna Faris reveals son Jack, 11 – whom she shares with ex Chris Pratt – is going through puberty: ‘He thinks he has armpit hair!’

Anna Faris is a mom rolling with the changes as her son grows up.

The actress, 47, who shares Jack, 11, with ex-husband Chris Pratt, 45, revealed the pre-teen is starting puberty.

‘He told me he thinks he has armpit hair,’ the comedic actress told Hoda Kotb and Justin Sylvester Monday on Today. ‘It’s happening.’

Faris was there promoting her upcoming film, My Spy: The Eternal City.

Sylvester advised the doting mom to ‘Get ready, honey. It is happening. Get all those hugs and kisses in now.’

The House Bunny star said she ‘misses’ her son being little, ‘sometimes, when you look at old photos, but I’m really loving this age.’

Still, the young man still needs his mom..

‘Something that makes me a little crazy about Jack, and I think most kids, is like, “Mom, where’s my backpack?’ when it’s right there.’

‘How do I teach him how to just look?’ she queried. 

The Estate star has some experience dealing with teenagers, thanks to her two step-children, whom she shares with her husband Michael Barrett.

The actress and cinematographer met on the set of 2018’s Overboard, got engaged in 2019 and eloped two years later.

Barrett is the dad to two children, a daughter 20, and a son, 17. 

‘When I first entered into their lives, I had no idea how to relate to them, so I remember trying to be really cool, like blasting music, Regulator, like when I would pick up… my stepdaughter [from school.] Of course, she’s mortified.’
