Hilary Duff knows how to please her Twitter followers!

Every time the 25-year-old shares a new photo of her son Luca, it falls nothing short of adorable. So how did the new mama and her little "monkey" spend time together over the weekend?

“Monkey and me at the park,” she captioned the photo posted to twitter on Dec. 7. The snapshot shows Hilary and her 8-and-a-half-month old baby posing in front of a playground.

The cutest part about this pic? The pair in matching denim! Hilary rocked thick black-rimmed glasses and a denim jacket, while her little man looked super sweet in a green button up cardigan, rolled up denim jeans and black sneakers.

Missing is Hilary’s hubby and Luca’s daddy, Mike Comrie. Though the pro hockey player missed out on this snapshot, who can forget about that father/son bonding one the blonde beauty shared just a couple of weeks ago? While visiting Mike’s native Edmonton, Canada, Hilary showed off her two men sharing a sled.

“It’s made [our marriage] stronger,” she’s said of her relationship with Mike following the birth of Luca in March. “Having a baby is a lot of hard work and you really depend on each other for a lot. There is so much love…you can’t imagine it until it happens to you and you look at your husband and you’re like, ‘We did this together.’”

We’re sure happy they welcomed Luca — and grateful Hilary loves to show him off for the world to see!
