As Haylie Duff prepares to welcome the birth of her first child, her younger sister, Hilary, has been supporting her every step of the way.

And on Sunday, the siblings were spotted enjoying brunch with Hilary's adorable son Luca - who turns three on March 20 - at popular eatery Granville in Studio City, California.

With her growing baby bump on prominent display, 30-year-old TV personality Haylie stepped out in a black maxi dress under a denim shirt, while she kept her feet cool in a pair of flip-flops.

Hilary, 27, opted for a pair of cropped jeans that were ripped at the knees, teamed with a brown animal-print sweater, grey scarf and white hi-top plimsolls.

Wearing her blonde hair resting loosely about her shoulders, the actress rounded out her ensemble with a quilted black Chanel handbag and a pair of oversized tortoise shell sunglasses.

As the sisters left their relaxed meal, Hilary stopped to buy her son a Spider-Man animal balloon - but he didn't seem too impressed, leaving his mother to carry it as they made their way to their car.

Later that day, Haylie took to her Instagram account to share a snapshot of herself posing with her mother and fiancé, Matt Rosenberg, as she picked out floor's for the growing family's new house. 

Hilary reportedly filed the divorce papers to end her marriage with 34-year-old former professional hockey player Mike Comrie last month.

Reports of the filing came just days after DailyMail.com revealed her husband of four years had been heard propositioning women at an exclusive Beverly Hills restaurant

TMZ reported that the blonde singer and actress cited irreconcilable differences and has hired divorce attorney to the stars Laura Wasser.

Meanwhile, Haylie and Matt, who got engaged in April last year after dating for 18 months, announced in December that they were expecting their first child.

The couple posted the news on her food blog along with a photo of two pink baby shoes

Haylie has made no secret of her pregnancy cravings for Mexican food and her passion for a daily green smoothie.

On her blog The Real Girl's Kitchen she posted a recipe for one of her favorite go-to health drinks packed with fresh greens, fruit and lemon juice.

She blogged: 'They have been my saving grace throughout my pregnancy. I love how healthy I feel after drinking one.'
