Los Angeles: Lady Gaga, who has often been pitted against Katy Perry by fans, seems unhappy with the `Roar` hitmaker`s green hair and horse prop during her Prismatic World Tour.

In what appears to be a jibe, Gaga tweeted to her over 41 million followers: "It looks like green hair and mechanical horses are the thing now."

Perry kicked off her world tour yesterday at the Odyssey Arena in Belfast, Northern Ireland, during which she rode a mechanical horse and changed into a green wig.

Interestingly, these props have featured in Gaga`s own performances. Gaga arrived on a giant fake white horse during last year`s American Music Awards wore neon green hair for a photoshoot recently.

The duo were previously compared when their singles `Applause` and `Roar` released on the same day in August. Gaga failed to recreate a magic with `Applause` while Kerry`s single was a hit.
