We cannot independently verify that reports of her breakup with Sebastian Stan are true. But we can tell you this for certain: Leighton Marissa Meester turns 24 today!
The actress and aspiring singer has come so far in recent years. Ever since we first laid eyes on this talented cutie as Blair Waldorf, we've fallen head over heels for her.
She's also made a splash in the music world, teaming up with Cobra Starship and releasing her own material. In 2011, she'll play the lead in the thriller The Roommate.
