25-year-old Hilary stepped out with her baby boy and her hubby in Los Angeles and appeared every inch the yummy mummy in a pair of leather-look trousers, a grey tank top and a quilted black bag.
She also kept things causal in pair of flip-flops and some sunglasses.
Meanwhile, 33-year-old Mike - a retired professional ice hockey player - looked cool in a pair of Converse trainers, some light denim jeans, a grey hoody and a baseball cap.
He also seemed to be getting into daddy duties by clutching a large black bag that no doubt had all of Luca's travelling essentials in it.
One-year-old Luca co-ordinated with his sports star dad in his own pair of adorable red Converse trainers, which he teamed with some cute yellow jeans and a shirt.
Hilary is often pictured running errands with her tiny tot, but this time it's nice to see the whole family out together!
Last month, the happy couple celebrated their third wedding anniversary and Hilary couldn't help but gush about her love for Mike on Twitter.
She wrote: "3 yrs ago today I married a wonderful man! So lucky we found each other. He also gave me the most precious boy I ever layed my eyes on!!."
The former Lizzie McGuire star also revealed some exciting news to her fans this week, as she posted a candid snap of herself in a recording studio and working on a new song.
Hilary was joined at the studio by songwriter and producer Billy Mann, who was helping her record a track called 'Better Days', which is thought to be appearing on her new album.
We wonder if little Luca has already had a special preview of the song?!
