Pia Whitesell is every inch the proud mother at son's graduation

The former Home and Away star shared a gallery of photos to social media at her 23-year-old son's graduation at Loyola Marymount University in Los Angeles, California

Pia Whitesell was every inch the proud mother over the weekend when she and husband Patrick attended her son Isaiah's graduation ceremony. 

The former Home and Away star, 42, shared a gallery of photos to social media that captured her at her 23-year-old son's milestone achievement at Loyola Marymount University in Los Angeles, California.

The Chilean-born actress and her billionaire husband beamed from ear-to-ear as she proudly posed with her eldest son and warmly embraced him.

Pia looked casually stylish for the outing in a black mini-dress paired with aviator sunglasses, as she proudly watched her firstborn receive his degree.

She captioned the post with some heartfelt words: 'One of the proudest moments of my life, watching you graduate.

'I didn't just see a graduation, I saw every step that brought you here... the hard choices, the growth, the strength, the resilience, the incredible young man you've become.

Isaiah, you make me proud beyond words. Watching you step into your future with that beautiful smile is one of my life's greatest privileges. The world awaits you, our Lil' Civil Engineer - Letsss goooooo! God bless you always, I love you.'

Pia has developed a reputation for being a hands-on mother and in January she revealed why being a stepmum to Lauren Sanchez's children was so rewarding. 

The Home and Away star's husband, Patrick, shares two children – son Evan, 19, and daughter Ella, 17 – with the former TV presenter, who is now married to Amazon billionaire boss Jeff Bezos.

Pia also shares sons Isaiah and Lennox, 19, from two previous relationships. 

'For me, it's honestly the best, most heartwarming thing to see the blending of four teenagers who were strangers just a few years ago,' she told Marie Claire Australia.

'We sit around the table every night, enjoying each other's company, having a laugh as we share our stories. We spent Thanksgiving together; how lucky are we to have all found each other?'

Pia also admitted she leans on her family during times of hardship, such as when they lost a house last year during the California wildfires.

It comes five years after Pia relocated to Los Angeles with her children and married Hollywood power agent and multimillionaire Patrick.

Since then, the glamorous star has seamlessly blended into LA life.

She accepted Patrick's proposal in late 2020 after he presented her with a spectacular diamond ring.

The solitaire oval diamond sparkler is estimated to be worth between AUD$1.10million and AUD$1.9million.

The couple tied the knot in May 2021.

Patrick is the boss of Hollywood talent and media agency Endeavor, formerly known as WME.

His client list includes the likes of Jude Law, Denzel Washington, Hugh Jackman, Kate Beckinsale, Matt Damon, Ben Affleck and Jake Gyllenhaal, with whom he shares both professional and personal ties.
