Taylor Swift likes her workouts solo -- as in she doesn't just book a trainer, she books a gym -- sorry Justin Bieber.
Here's the deal ... Justin was at Dogpound Gym in West Hollywood with a bunch of people, but then Taylor and her crew rolled up.
We're told everyone -- including JB was asked to get the heck out of the gym -- because Taylor had an appointment. Justin's security team was approached and asked to leave, but JB's team held firm and said he was going to finish his workout before taking off.
We're told Justin, who did not have an appointment, finished -- although he was mostly goofing around and dancing -- and left ... but he had no idea it was Taylor who had requested the gym be cleared. Once he left, everyone who remained was asked to leave.
One source connected to the gym tells us Taylor did indeed have an appointment with a trainer in the gym ... and the appointment was to train alone. Justin just happened to be in the wrong place at the wrong time.
Katy Perry was snapped at Wednesday’s “American Idol” premiere in LA wearing a blush pink metallic animal-print minidress by Stella McCartney ($2,130) with wide, fluttery sleeves and a matching rope belt.
If the frock feels familiar, it’s likely because Taylor Swift — Perry’s once-foe, now-friend — chose the very same one for a December appearance on “The Tonight Show Starring Jimmy Fallon” to promote “Cats.” A longtime fan of the British designer’s, the 30-year-old musician recently collaborated with McCartney on a clothing line and pop-up shop tied to her latest album, “Lover.”
The two pop stars, who famously feuded for years before burying the hatchet with baked goods, styled the dress quite differently.
True to her maximalist M.O., 35-year-old Perry played up the piece’s shine with more sparkling accessories, including crystal-studded Jimmy Choo heels ($995), a bedazzled statement necklace by Lele Sadoughi ($325) and starry earrings from Maryjane Claverol ($258).
