Glamorous Sunrise nutritionist Sarah Di Lorenzo addresses rumours she’s dating newly-single Mark Beretta – who became a sex symbol following split from wife

Sarah Di Lorenzo has been left stunned by rumours she is dating her Sunrise co-star Mark Beretta.

The celebrity nutritionist, who regularly appears on the breakfast show, found herself embroiled in conversations about her love life after the TV star ended his marriage.

“Mark and I are colleagues and friends and he’s such a great guy – but I couldn’t believe it,” the single mother of three says Stellar Magazine this week.

“It was ridiculous considering we had never had a cup of coffee before,” she continued.

“I was shocked and completely distraught that someone would just make something up.”

Sarah works as a nutritionist for Channel 7 Sunrise and Weekend Sunrise, as well as being a busy mum, and says she is happily single.

“There’s nothing sad about not dating. I love being a single mom and I’m really happy to spend the rest of my life alone,” she said.

“I want to make women realize that you don’t need a partner to appreciate your life and find happiness.”

Mark has become one of Sydney’s most popular bachelors after splitting from wife Rachel last year after 22 years of marriage.

The 57-year-old sports reporter and his former partner Rachel, whom he married in 2001, confirmed they quietly split last year.

“Earlier this year, after much thought and 22 years of marriage, Rach and I came to the conclusion that a divorce was best for us,” Beretta told Daily Mail Australia through a Seven spokesperson.

“We remain good friends and our two children and grandchild remain our focus and priority as we move forward with love, dignity and respect.”

The couple, who met in 1999, have two children: daughter Ava, 19, and son Dan, 16.

There were already signs of trouble in the run-up to the split: the couple put their house in Mosman on the market in February.

They eventually sold their Balmoral Slopes home in May for $13 million.

They had to settle for less than their original expectations of $15.5 million, lowering the asking price by $1.75 million.

Fans are now wondering who will win Mark’s heart, with insiders previously claiming that the busty celebrity nutritionist Sarah is a contender.
