The Block contestant Suzi Taylor has been rushed to hospital after collapsing on set yesterday.

The 44-year-old was found unconscious in South Yarra in Melbourne around 10.50am and an ambulance was called immediately.

She was taken to the Alfred Hospital and is believed to be in a stable condition.

News.com.au reports that Nine Network Australia spokeswoman Victoria Buchan said Taylor was suffering from exhaustion.

“ Suzi was suffering from exhaustion after a busy day with The Block open for inspections,” she said. “She was taken to hospital yesterday, but has since been discharged and is resting.”

Taylor, a Gold Coast real estate agent, is partnered with her friend Yvonne Cosier, 39, on the show.

Dubbed "the single mums", they are the oldest team on the current season, and have never undertaken a renovation project before.

Taylor, a mum of three, has made plenty of headlines recently.

In September, she appeared on A Current Affair, where she spoke about posing nude for Penthouse Magazine in the '90s.

When she was 19, Taylor became ‘Penthouse Pet’ of the year, and she said she had no regrets.

"I'd be crazy to think they [the pictures] wouldn't come back one day, especially doing something as big as The Block...I have no regrets about Penthouse, it gave me a stepping stone to a lot of work," she said. "I was hanging out with rock stars, going to celebrity grand prix, getting invited to parties and social events, it was a lot of fun for 19-year-old... it was a hoot."

Taylor also admitted to being INXS star Michael Hutchence's close friend and ‘Gold Coast girl’.

She told A Current Affair: "Yes, you could [call me his Girl on the Cold Coast] but I'm sure he had a girl in every port... Look, we met when Michael needed company in his life, he would give me a call...and we'd have a lovely catch up."

We wish Suzi a speedy recovery.
