Luca is growing up! The former Gossip Girl actress showed off another cute snap of her little one Thursday

Seriously…can this kid get any cuter?

Hilary Duff treated fans to yet another adorable picture of her son Luca, this time showing her tiny tyke lounging on a yellow blanket. 

"Luca!," the actress tweeted Thursday, along with the Instagram snap of her five-month-old little one.

Duff recently referred to motherhood as "the most incredible thing," telling E! News in June, "it softens you so much. I feel like a big mushy ball."

"Whoa I have a cute baby! ‪#crazyinlove," Duff tweeted Tuesday.

We couldn't agree more.
