They did co-star in the Disney Channel movie "Lemonade Mouth," which sparked rumors of a real-life romance due to their on-screen chemistry. However, both actors have remained tight-lipped about their personal lives, and neither has ever confirmed a relationship with the other.
It's important to remember that actors often have great on-screen chemistry without necessarily being romantically involved in real life. The rumors surrounding Bridget and Luke might have stemmed from their playful interactions during interviews and promotional events, but there's no concrete evidence of a relationship.
