Actress Hilary Duff posted on Twitter Wednesday a photo of her son posing in a plastic cop car.

Luca, 1, sat in the faux vehicle with his right hand grasping onto the steering wheel and his eyes shifting sidewards.

"Ummm...I'm cute!" the 25-year-old mom tweeted, along with another photo of her son dressed in a striped, long-sleeved cardigan, denim trousers and tan suede moccasins. Luca wore a printed bandana around his neck to add to the outfit. 

"Pullover.... No it's a cardigan but thanks for noticing lol," she jokingly tweeted.

Later, Duff, who recently released her new romantic novel True - was seen carrying her toddler around town, bringing him to his baby class in Sherman Oaks, California.

The mom wore a striped red beanie hat, grey knit pullover sweater, skinny corduroy pants and brown leather boots. She was carrying her son in her left arm as she held onto a water bottle with the same hand, resting her white designer bag on her right shoulder.

Duff recently posted another message exemplifying her son’s learning skills:
