Richard's wedding proposal in 1997
In his birthday message, the actor-turned-politician briefly looks back to the day he proposed to Lucy on the eve of her birthday in 1997.
Lucy shared the same memory in her Instagram post when she and Richard celebrated their 21st wedding anniversary early this year.
Published as is, her caption read: "December 1997.
"We were in the balcony of my parent's home in Carlota Hills, it was the eve of my birthday and a handful of us were around a small table, a view of the sea before us.
"When the clock struck midnight Richard pulled me close, locked me in his piercing gaze, and asked me to marry him. I said yes in a heartbeat.
"I was in denim shorts, a t-shirt, slippers. He was in shorts, a shirt, sneakers.
"The ring was not in a box or pouch, it was just swimming loosely in his pocket for hours the whole evening. Until he pulled it out to slip it on my finger.
"He took this photo moments after we got engaged. And if I look dazed it's because I was.
"I was going to marry this man I have loved since I was 12 years old, spend forever with him, the love of my life."
Richard and Lucy have a 19-year-old daughter named Juliana.
