Matt Damon Wants His 12-Year-Old Daughter To Babysit — So He Can Get Some Sleep!

Being a dad to four girls (including a newborn) is pretty tiring and Matt Damon has decided he needs a break! It’s time to hire a babysitter — and he has just the girl in mind!

We can only imagine how tiring it must be for Matt Damon and his wife Luciana, to take care of four girls day in and day out! Matt loves being a dad, but it’s definitely wearing him out! That’s why he’s ready to pass the babysitting torch to his stepdaughter, Alexia!

Matt’s good friend Ben wants to have another baby! Exclusive!

“The 12-year-old is getting close to being full-on babysitting age,” he said on The Late Show with David Letterman. “Then I can just retire and go take a nap, because I’m pretty tired!”

Matt and Luciana just welcomed a daughter, Stella, on October 20 who joined Alexia and their two girls, Isabella, 4, and Gia, 2. Three kids under the age of 5 — no wonder Matt’s run down! Balancing a career and fatherhood is hard, but we’re sure it’ll be much easier to handle now with his new babysitter! We hope he pays Alexia well!
