The GMA-7 actor was a presenter for the winners of the Miss Millennial 2019 segment on the noontime show.
Alden was tasked to present the second runner-up of the contest, along with SKAL International chairman Robert Lim Joseph Jr.
However, EB host Pia Guanio did not acknowledge Alden and only introduced Mr. Joseph Jr.
Leysam Sanciangco, Alden's handler, noticed the gaffe and wrote on his Twitter account: "Di man lang binanggit haha! Parang pahabol na lang ah?"
After Pia failed to introduce Alden, co-host Paolo Ballesteros mentioned Alden after second runner-up Annabelle McDonell was awarded.
"Congratulations! Thank you din, Alden," said Paolo.
Pia used Instagram to address the issue the following day. She made an appeal to Alden by writing: "Please tell your fans not to get mad na! Wag na mag-away! God bless you all!"
Subsequently, Pia edited her Instagram post, which now has the caption: "So proud to be part of a segment that aims to show how beautiful our country is."
The hashtag #LabyuALDEN became a top trending topic on Twitter as fans commented on the blunder.
