On Valentine's Day this year, Richard called into Sunrise live on air to give her a romantic surprise.

“It's Rich! Happy Valentine's Day,” Richard said.

“I'm much more romantic than Sammy,” he added. “You told me you wanted a surprise.”

Richard went on to reveal that he had made Sam a gift for the special day and explained how he had been trying to “throw her off the scent” to surprise her.

The happy couple.

Speaking to WHO magazine's Sexiest People issue, described Lavender as a “decent” and “very honest” man and added that the most attractive thing about him was he's “comfortable in his own skin”.

Richard lives in a 40-hectare property in Bowral, NSW, the same country town where Sam owns a $2.2 million five-bedroom retreat.

It's believed the couple spend most weekends together in the Southern Highlands, while Sam returns to her $2.5 million Bondi home in the week.
