Hilary Duff took her baby boy Luca Cruz Comrie for a dip with Aunt Haylie Duff, and they looked like they were having so much fun together swimming! The actress, who loves being a hands on mom and going out with her son, shared the adorable pic on her Twitter.

In the adorable pic, Hilary is in a green bathing suit kissing Luca’s cheek as Haylee holds him, wearing a black bathing suit. The 11-month old’s blond hair is styled in a wet mohawk. So cute!

The former Disney star, who married NHL hockey player Mike Comrie August 2010, welcomed baby Luca in March 2012. It’s the couple’s first child together, but with how much Hilary loves being a mom, we’re sure they’ll have more!

Baby Luca Is Now Walking

The actress tweeted on Feb. 28 about her baby’s huge milestone!

“Well I officially have a walking baby on my hands!” she announced. “It’s hilarious…the wobble makes it look like he’s 3 drinks in!”

Luca Cruz: The Meaning Behind The Name

“We had the names Cruz and Luca on our list with some others and decided at the very last minute what it was going to be,” Hilary explained to Parade magazine. “We just liked the way it sounded together.”

Luckily, Mike is such a hands-on dad!

“[Mike is] not going to do everything the way I would do it — and vice versa — but we just want the best for Luca,” she said. “It’s helped me appreciate Mike’s role in his life and that we’re doing things with the most love that we can.”

Luca’s blonde hair matches his former Disney Star mom’s bright hair, but his handsome face looks more like dad Mike Comrie!

Hilary Duff Reveals The Story Behind Luca’s Name

“We had the names Cruz and Luca on our list with some others and decided at the very last minute what it was going to be,” she told Parade magazine in April just a few weeks after giving birth. “We just liked the way it sounded together.”

“Afterwards we found out his name means ‘bringer of light,’” she added. “I love that.”

Hilary Tweets Adorable Pic

On Jan. 5, the star tweeted a pic of her little man eating a yummy croissant saying, “Please don’t bother me while I eat my croissant.” So cute!

But this isn’t the first time Hilary has tweeted about her son’s love of food. The proud momma tweeted “Luca drops all his food on the floor for the dogs but the kid will NOT share his blueberries!” on Jan. 3. Looks like Luca is a foodie in the making!

Luca, who will be a year old in March, is clearly the apple of his mother’s eye. The doting mom also tweeted on Dec. 29, “Having a child is so special! I know it’s not NYE yet but I’m just thinking about my year and feeling so blessed for my precious boy❤ &Mike!” Aww!

Hilary’s Hubby and Baby Happiness

The former Lizzie McGuire star keep her fans and Twitter followers updated not only on her growing son, but her marriage, as well.

Hilary’s other main man is husband Mike Comrie, an NHL player. The two married in August 2010 in California and welcomed their first baby, Luca, in March 2012. The two seem incredibly happy together!

We think Luca has grown up so fast! But we can’t tell who he looks more like: Momma Hilary or Daddy Mike. What do you think, HollywoodLifers? Who does Luca look like more?
