Regine Velasquez was one of Alden Richards's guests during his Adrenaline Rush concert last Friday, September 21.
During their spiels, Regine recalled working with Alden in the 2014 reality competition Bet ng Bayan.
She told the audience, "Alam niyo po, si Alden, nagkasama po kami sa Bet ng Bayan. And that time, you were already... you did the soap of Marian already [Carmela]."
Alden answered "Yes po, pero that time I was doing Ilustrado at the same time."
Regine then said, "But you know, let me just tell you, noong time na yun sikat na po si Alden. Pero mas lalo pong sumikat.
"But I just want to say he has never changed. He is the same the way I met him before, bago pa yung mga Carmela, bago pa AlDub.
"He was already like this and he is still like this so I'm so proud of you, sweetheart and thank you for having me. Don't ever ever change because you're such a wonderful person."
Alden then told the veteran singer, "Thank you po, Ate. To share the stage with you is a dream come true po."
Regine then said, "Uy, by the way, may isang nagmamahal sa 'yo dito at birthday niya."
Alden then greeted Regine's mom Teresita Velasquez, or Mommy Tess, a happy birthday, who was at the audience.
Mommy Tess is known to be a "super super fan" of Alden Richards and Maine Mendoza's love team, as also mentioned by Regine during the concert.
The Asia's Songbird then recounted how it all started.
"My father kasi passed away some three, four years ago. And when he passed away, siyempre, malungkot si Mommy.
"Dun yung nag-umpisa yung AlDub! Super siyang na-in love sa inyo ni Maine.
"One day, sabi niya sa amin, 'Uy, alam mo naka-move on na ako.'
"So malaki ang pasasalamat ko at utang na loob namin sa AlDub.
"Di ba, noong birthday niya, sinurprise niyo? And that was her best birthday ever! She loves you and thank you for bringing happiness to my mother and to others who are here."
Alden then responded, "We will never ever get tired of making Mommy Tess and everyone else happy. Kami po ni Maine."
Last year, Regine's cooking show Sarap Diva aired AlDub's birthday surprise for Mommy Tess.
