Hilary Duff opted for a casual, cool look as she went to lunch with her son Luca on Saturday.

The 35-year-old actress wore a black summer dress, white sneakers and a Christian Dior crossbody bag for the outing.

The Lizzie McGuire star – who recently revealed she’s inspired by Gwyneth Paltrow’s diet – accessorised in sunglasses, gold hoop earrings and a matching gold necklace.

The mother-of-three wore her light blonde locks parted in the middle and tied back in a bun.

Hilary took her 11-year-old son to the Yeastie Boys’ food truck before going to a baseball game.

Luca wore a black football uniform for the lunchtime outing.

The singer shares Luca with her ex-husband, former professional hockey player Mike Comrie, 42, who she was married to from 2010 to 2016.

She also shares Banks Violet, four, and Mae James, two, with husband Matthew Koma, 35.

The Texas-born star married Koma in 2019 at her LA home.

Duff was also pictured with a cup of coffee in hand, after recently admitting that she drinks caffeine in the morning to “satisfy my hunger”.

She shared that she takes inspiration from Paltrow, 50, when it comes to staying slim.

The Disney Channel graduate revealed this week on the Lipstick on the Rim podcast that she often skips breakfast to keep hunger pangs in check.

“Sometimes I try — you know, Gwyneth is in trouble for saying that — but sometimes I try to just have coffee in the morning and satisfy my hunger,” she told host Molly Sims.

Earlier this year, Paltrow, 50, was accused of promoting “starvation” after she revealed that she eats mostly bone broth and vegetables alongside intermittent fasting.

Duff explained that she tries not to start her day with a meal because she often wakes up “really hungry.”

But she sometimes breaks the rules when packing school lunches for her three children.

“If we’re being honest, yes, I eat a chicken nugget in the morning while I pack up lunch and there’s one left over. ‘Let it down the hatch!’ said duff.

The Raise Your Voice actress insisted she eats “a lot of calories” throughout the day.

She favors “super clean,” nutrient-dense foods and even includes plant-based options on her menu.

Right now, Duff is “obsessed” with cauliflower slices, which she often tops with avocado or vegan sausage, and overnight oatmeal is a staple in her fridge.

Duff is also an avid fitness enthusiast who goes to the gym four to five times a week.

She told Sims that her personal trainer had her do high-intensity interval training alongside weightlifting.

She gave her fans a close look at her enviably toned figure while gracing the cover of Women’s Health Australia in January 2023.

She shared more details about her exercise regimen and how “macro counting” has kept her in shape while still allowing her to enjoy the foods she loves.

Duff can still eat things like “chocolate and bread” as long as she keeps track of the amount of protein, carbs, and fat she’s eating each day.
