A very thin Katy Perry was photographed at a Christmas event

Fans of the performer Katy Perry are concerned about her rapid weight loss. The appearance of the artist began to be widely discussed online after recent photographs.

The photos were taken at the iHeartRadio Q102 Christmas event in Philadelphia. The 40-year-old star appeared unusually slim, reports Dailymail.

The performer wore a revealing red sequined dress that highlighted her significantly reduced waist. The photos also show her sharp cheekbones and folds around her mouth.

Fans have been speculating for days that the singer is using a special diabetes medication, which has become popular among celebrities seeking the perfect figure (weight loss is one of the side effects of the drug).

However, people close to the star deny such claims. They say Katy has simply increased her physical activity in preparation for the upcoming tour.

Her husband, actor Orlando Bloom, known for his role as Legolas in the "Lord of the Rings" trilogy, supports her. The couple follows the same diet and workout regimen.

Her transformation is not related to weight loss drugs. Katy is just working hard and eating better than before.

Zoomboola.com reminds us that Perry is not the first celebrity to lose weight dramatically this year.

In mid-March, net users discussed the updated appearance of singer Christina Aguilera. She attended a social event where journalists photographed her.

In the photos, Christina does not look her age (she is 43 years old). Online comments suggest that Aguilera suddenly looks 20 years younger. Many speculate that the diabetes medication is involved here as well.

In the same month, paparazzi photographed a dramatically slimmed-down television host Oprah Winfrey.
