Sunrise host Samantha Armytage has announced her engagement to boyfriend Richard Lavender by flashing her diamond ring on an Instagram post to her 230,000 followers.

Armytage has been dating Lavender since at least November last year, after they officially confirmed their relationship to the media – and it seems to be going well.

“What a year …” Armytage captioned the photo which she posted to Instagram.

Showing off her engagement ring, the 43-year-old was rugged up in a beanie and puffer jacket.

The couple have kept their relationship largely under wraps.

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 said he had been trying to “throw her off the scent” to surprise her.

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 owns a 40-hectare property in Bowral, NSW.

Sam also owns a $2.2 million home in the same country town.
