The 'Fireworks' songstress was seen on the set of comedy sketch TV series, the 'Kroll Show', on Tuesday (4 June) and looked hot to trot in a flattering patterned pencil skirt and matching cropped top.
She teamed her chic ensemble with a pair of black strappy heels, a few silver rings and some sunglasses.
Given that she always manages to turn heads with her fashion choices, we can imagine Katy has numerous guys queuing up for a date.
However, she is apparently now back in the arms of her ex beau, John.
Katy, 28, is speculated to have rekindled her romance with the notorious ladies man and Grammy award winning musician after he was seen leaving her house and heading to the recording studio recently.
The on-off couple were said to have been getting cosy at a Memorial Day BBQ last month too, but according to E! News, they are keeping their reunion "casual" at the moment.
John and Katy first got together last summer but split up earlier this year.
Over the last couple of months, Katy is said to have gotten close to Twilight actor, Robert Pattinson, which is alleged to have put an added strain on her relationship with John.
