Maria Alejandra Samaniego was devastated when she literally walked in on her boyfriend, Pabil Muniz Quintanilla, 27, in bed with another woman.
But rather than hide away ashamed, she decided to hit him where it hurts and truly get her revenge - by destroying his luxury car.
After storming out of his home on finding him cheating, she snuck into the garage area with a friend, and, taking a permanent black marker in her hand, wrote some seriously cutting messages all over the prized vehicle.
In the comments she accuses him of being bad in bed, a ‘junkie loser’ and questions the size of - you guessed it - his manhood.
Her friend, Valeria Cazares Aranda, 28, filmed the entire thing, and later posted the footage to the internet for all to see.
Eek! We bet he regrets that one.
Would you ever seek revenge on a cheating ex? Or is it better to rise above it?
