Given the exclusivity clause in most stars' contracts with their respective networks, we rarely see a Kapamilya being paired with a Kapuso in a project.
Hence, the sight of ABS-CBN and GMA stars together in an event or even their simple exchange on social media usually hits the headlines.
But friendship knows no boundaries even in showbiz.
Here's a list of celebrity barkada and squads that are not affected by the network war.
Julia Barretto and Gabbi Garcia
These two were barkada in an all-girls school.
To this day, they are still in touch, and they attend each other's parties.
Kristoffer Martin and Paul Salas
Good friends and gym buddies, these guys are each other's plus one.
Paul gets to attend some Kapuso events.
See how the former child star felt at ease in the company of GMA's former tween stars.
Likewise, Kristoffer gets to mingle with Kapamilya teens such as Barbie Imperial (4th from left), Chie Filomeno (middle), and Sue Ramirez (third from right), a close friend of Paul.
Jona and Kris Bernal
Though the singer transferred to ABS-CBN in March 2016, Kris said she'll be there for Jonah "through thick and thin...til we find our forevers."
The Kapuso actress watched the ASAP singer's concert early this year.
Sandara Park and Katrina Halili
When Sandara celebrated her birthday here in Manila last November, the Kapuso actress went to ABS-CBN compound to personally greet the K-pop star.
The two became friends while on the set of action fantasy film Super Noypi in 2006.
When Dara left for South Korea, they have remained in touch via Twitter.
Angelica Panganiban and Glaiza de Castro
They have been calling each other "amigah" for 15 years. Wow!
Camille Prats and Kaye Abad
These ladies have been friends for 20 years now.
Even after Camille became a Kapuso in 2004, they never forgot to invite each other to their life's milestones and celebrations.
Rufa Mae Quinto and Mariel Padilla
They became close because of Willie Revillame's defunct TV5 show Wil Time Bigtime, where they were co-hosts.
Before she got married, Rufa Mae was a co-host of Willie in GMA's Wowowin, while Mariel returned to ABS-CBN via the noontime show It's Showtime. That was in 2015.
Almost two years later, both of them are moms now, not to mention, "breast friends."
Iza Calzado, Sunshine Dizon, and Karylle
Iza and Sunshine used to be the primetime queens of GMA.
They topbilled about six TV series, and took turns in playing the bida and kontrabida.
When they played Sang'gres in the original Encantadia, Karylle became part of the squad.
Iza and Karylle are now with ABS-CBN.
Anne Curtis, Isabelle Daza, and Solenn Heussaff
Though Anne and Isabelle are Kapamilya and Solenn is a Kapuso, these three ladies (together with Georgina Wilson and Liz Uy) have had endorsements together.
Off cam, they are travel and fitness buddies.
Jericho Rosales, Ryan Agoncillo, and Drew Arellano
These guys were brought together by their love for motorbikes. They call themselves The Brap Pack.
Eventually, they became magkumpare (their latest inaanak was Drew's baby) and their wives became close friends.

Recently, Paulo Avelino (middle) and Gab Valenciano (left) started joining their bike and breakfast activities.
Kuya Kim Atienza (not in photo) was spotted, too.
Kim Atienza and Dingdong Dantes
The actor and host became friends because of triathlon.
Recently, they're becoming biking buddies, too, along with The Brap Packs.
Also in photo: Gretchen Fullido, who did the swim leg of their recent race in Subic, Zambales.
Regine Velasquez and Jaya
Their friendship started in 2000, the year Jaya joined SOP.
Almost 17 years later, Jaya is now a Kapamilya while Regine remains a Kapuso.
But the magkumare still see each other regularly.
