Pop starlets Lady Gaga and Katy Perry have been involved in beef rumors in the past, but Gaga's latest tweet has fans puzzled.
Gaga tweeted Thursday, "It looks like green hair and mechanical horses are the thing now." She also added the goofy eyes emoticon.
Perry, who began her 'Prismatic' tour features the "Birthday" singer entering the show with a mechanical horse. Gaga used the technique during last year's American Music Awards. Gaga has also sported green hair similar as Kerry did as she showed to fans on Instagram.
Do you think it was just an observation or more?
