Ready to log more hours at work, Katy Perry was all smiles as she arrived at a studio in Los Angeles on Thursday afternoon.

The recently engaged “I Kissed A Girl” singer strolled into the entrance, seemingly having something up her sleeve for her co-workers, as she tweeted, “YES I beat them here! Now to setting traps!”

Meanwhile, Miss Perry took to her Twitter account to shoot down pregnancy rumors in her oh-so-eloquent way.

She replied to a comment from producer/songwriter Lukasz Gottwald, writing, “ur gonna make me cry, maybe that’s my period tho. THAT’S RIGHT I’M BLEEDING.”
