She may be separated from her multi-millionaire American talent agent boyfriend, Patrick Whitesell, due to the coronavirus pandemic.

The former Home and Away star stunned on the night in a sunny yellow Rebecca Vallance dress, which showed off her cleavage and accentuated her toned figure.

She let her frock do the talking by wearing minimal jewellery and showed off her natural beauty in barely any makeup and her hair out in loose soft waves.

Pia was joined by several friends at popular Italian restaurant Cafe Nino in Woollahra. She also had a Zoom party with some of her friends and family who could not make it, including her brother Jesus.

Earlier in the day, the exotic beauty was treated to bunches and bunches of flowers, including a huge bouquet of white roses from her beau Patrick.

The Australian actress marked the occasion by sharing a professional, black-and-white photo of herself to Instagram.

Pia flaunted her beautiful smile in the image, and revealed in the accompanying caption that she was smiling out of ‘gratitude’.

‘BIG gratitude smile this week! Another year older,’ she wrote, adding the hashtag #ThisIs37.

Also joining in on the birthday celebrations was her youngest son, Lennox, 14, who shared a tribute to his mother on his own Instagram account. 

‘Happy Birthday mum. Love you,’ he captioned the photo.

The birthday celebrations come after fans were stunned to learn Pia’s real age last month.

The mother of two’s age has often come under scrutiny, with many fans suspecting she may be much younger than she claims to be.

But after being pestered by fans on Instagram, the Chilean-born beauty revealed at the time she was 36, and turning 37 in November.

The revelation came as a shock to some people, as Pia still physically appears to be in her mid-twenties.

In photos taken with her teenage sons, Lennox and Isaiah, 17, Pia looks more like their big sister than their mother.
