In the wake of Charles’ birthday disaster, Aria takes a moment to ponder where the girls’ plan went wrong. But here’s a better question: Why did she ever think it would go right?

Charles' birthday party goes awry.

I’ve been thinking… if this whole ‘local terrorist’ thing doesn’t pan out, Charles DiLaurentis could forge a pretty sweet fallback career as a party planner.

The Pretty Little Liars are headed to prom — for real this time! — and TVLine has your first look at Aria, Hanna, Emily and Spencer in all their formal glory.

Rule number one of being a Pretty Little Liars fan: Don't. Trust. Anyone.

Hanna Marin’s always been a bit of a klepto — don’t forget we first saw her swiping sunglasses in the pilot — but grand theft auto? I never thought I’d live to see the day!

Teen love Pretty Little Liars, so it's no surprise that the beloved teen murder mystery is scoring big at the 2015 Teen Choice awards.
