Lauren's friends from showbiz immediately took to the comments section of her post to extend their congratulations.
Actress Maja Salvador wrote, "Awwwww congratulations [three heart emojis]"
Lauren is managed by Crown Artist Management, the artist-management company owned by Maja.
"Congratulations!!! Happy for you [heart emoji]" remarked Maja's husband and businessman, Rambo Nuñez.
Host-model Marc Nelson commented, "Whaaaaat?!? No waaay! So so happy for you! [three heart emojis]. (And loving your looks in the OG throwback pic [laughing and two clap emojis]"
Leila Alcasid, daughter of singer-actor and host Ogie Alcasid with ex-wife and former Miss Universe Australia Michelle van Eimeren, enthused, "Omgggg congratulations [four heart emojis]"
Lauren is close to her half-brother James and admitted to joining show business because of him.
"I’m tied to the family name, which is definitely one thing. And James did in a way present me on his Instagram, so. And it’s nothing that I would regret anyway, it’s… I’m thankful for it," she said in 2016.
Lauren was working in Australia and had plans to enter the corporate world in the Philippines but decided to pursue show business instead.
“I suppose if you wanna be a real artista, you gotta be an all-arounder," said Lauren.
Added Lauren, "I started to think, ‘You know what, this is actually something that I could do. And I’m confident now.’”
Lauren was also close with James's now ex-girlfriend Nadine Lustre.
Fans, in fact, labelled their friendship "LauDine" — a combination of Lauren and Nadine's names.
Following the confirmation of James and Nadine's breakup in January 2020, Lauren posted a photo with Nadine on Instagram.
"Please keep the sisterhood bonding especially the love," a netizen told Lauren.
