At a glance
"Best weekend ever!"
This was how First Lady Liza-Araneta Marcos described the weekend as she and her husband, President Marcos, capped their anniversary week with some quality time together.
The First Lady uploaded a photo of the two of them on Instagram with the President hugging her from behind.
"There’s nothing like spending quality time with your better half. Best weekend ever!" she wrote on Sunday afternoon, April 21.
"[Thirty-one] years and counting," she added.
Araneta-Marcos earlier defended the President from criticisms that he was "under the saya," or whipped, saying she even gave up her law firm to support him.
The First Couple were married on April 17, 1993, at the Church of St. Francis in Fiesole, Italy. They have three children, including Ilocos Norte First District Representative Sandro Marcos.
In a speech in New Jersey last year, the President became emotional as he reminisced about his life in the United States, mainly how he met his wife in New York.
"Sa New York kami nagkakilala. At siguro mga tatlong taon niya akong niligawan (We met in New York and she courted me for three years)," he said.
According to Marcos, he would visit his mother, the former First Lady Imelda Marcos, in New York from Philadelphia in 1986 and meet Araneta-Marcos, who was already working in the Big Apple as a lawyer for about six to seven years.
"Nagkakilala kami in court, sa korte. Habang hinahantay ko ‘yung kaso ng mother ko, siya naman ay bumibisita dahil kaibigan niya yung isang abugado namin at ayun (We met in Court. While I was waiting for my mother's case, she would visit because one of our lawyers was her friend. That's it)," he said.
