Semerad Twins, Anthony and David, inside the PBB house as fake "swap housemates!"

The Semerad twins, Anthony and David Semerad, have entered the Pinoy Big Brother (PBB) house last night as "fake housemates" from Czech Republic.

Anthony and David Semerad are given by Big Brother the mission to make the housemates believe that they are swap housemates from Big Brother Czech Republic (Vertý Bratr).

Kuya has also reminded the twins to make sure the housemates would not discover that they're half-Filipino.

Anthony and David John Semerad are 19-year-old Aussie-raised Filipino-Czech twins. (Hope you didn't get confused.)

They stand so tall at 6'5". Wow!

The Semerad twins are basketball players, have previously played for San Beda Red Lions and just last December, they moved to the Ateneo Blue Eagles.

They are also among the newest Bench endorsers and have appeared already in 2 latest ad campaigns for the said clothing brand.
