In a series of videos posted to Twitter, the pop singer and her brother Austin, 24, played what they called "Easter Egg Battles 2016." But really, it's a traditional Easter game called egg tapping.
The goal? Crack the opponent's egg without cracking your own.
As the battle waged, Swift, 26, realized she wasn't the best at this game. She even claimed her egg was faulty.
"This isn't fair! I used this one last round," she said to her brother in one video captioned, "A devastating loss."
Swift also accused her brother of cheating.
"That's against the rules!" she said to him, while he laughed in his victory.
