Ogie also marked the occasion by sharing his anniversary greeting for his better half on his Instagram account.

"11 years married today. Loving you is a blessing and being loved by you is pure heaven," he said. "Happy anniversary my love. Having you in my life is the biggest gift from above. I love you with all my heart, Regine."

Regine and Ogie tied the knot in a private ceremony in Batangas in December 2010, after three years of dating.

In a previous interview, Regine, who is known as the "Asia's Songbird" of local showbiz, revealed going on her first date with Ogie when she was only 18 and he was 22.

“Pero it was a group date," she explained. "Niyaya niya ako makipag-date. I was even with my father because I was young and taga-Bulacan pa ako."

"[But] then, narealize daw niya na I was so young. Wala sa isip ko 'yung mga ganoon, mga boys. So hindi na niya ako niligawan."

According to Regine, she and Ogie didn't see each other for a long time, until they worked together on the Sunday variety show SOP.

“That's how everything started," she said. "Parang naging mas close kami. Sa 'SOP', 'pag darating ako, he’s the first person I look for kasi makwento siya, marami siyang tsismis."

However, the Asia's Songbird said it took a while before she developed romantic feelings for Ogie.

“Matagal. Basta nga ganun, parang he started calling me. Because we were just really friends. We had no intention of falling in love. We were just really good friends… Parang 'yung time na 'yun, ako na lang yata 'yung artista na walang cellphone. Nung nagkaroon ako ng cellphone, I think he’s one of the first persons I texted. I congratulated him, it was his concert. And then after that, we would have an exchange na. Nagte-text na kami lagi. Sumunod dun 'yung tawagan na,” she said.

Nevertheless, Regine said she was not surprised when Ogie confessed his feelings for her.

“I was kind of expecting it and I was also kind of wanting it to happen pero hindi ako sure because he was married. And then it happened,” she said.

In the interview, the singer also admitted that she and Ogie had a rocky start to their relationship.

“Hindi siya masayang umpisa. Madami kaming pinagdaanan," she said. "But in the end, it all worked out and now we are here. We are married."

Last year, Regine and Ogie marked their 10th wedding anniversary with a song entitled "Hope."
