There have been rumors that Andrea Brillantes caused the breakup between Karina Bautista and her boyfriend, but these claims largely come from fan speculation rather than verified facts. The situation is complicated by overlapping connections between Andrea, Karina, and actor Seth Fedelin, who had professional ties with both actresses.

Karina Bautista and Seth Fedelin appeared together in the 2019 reality show Pinoy Big Brother, where their chemistry was well-received by the audience. Fans even began shipping them as a couple due to their close bond. Later on, Seth was paired with Andrea Brillantes, and the two became a popular on-screen couple. This shift sparked various fan theories, with some speculating about off-screen romantic developments. As a result, Andrea’s growing closeness to Seth may have led to rumors that she was involved in Karina’s personal breakup.

However, there is no concrete evidence to support these claims. It is important to remember that, in the entertainment industry, such rumors can quickly gain traction without any factual basis. Both Andrea and Karina have not publicly acknowledged any serious issues or conflicts related to their relationships​

These speculations are common in showbiz, where the lives of celebrities are constantly under scrutiny. Nonetheless, it is essential to approach these rumors with caution, as they are often exaggerated and do not reflect the real situation.
