Mariah Carey recently unveiled the cover art for her greatest hits album, "#1 to Infinity."

Although her fans shared their excitement over her new album, they also took notice of the alleged use of Photoshop in the cover art photo, Daily Caller reports.

Carey's "#1 to Infinity" cover art features the singer in an all-black cut-out dress with a plunging neckline to reveal her frame, which fans are claiming has been digitally altered. 

In her recent performances, Carey has appeared curvier than how she looks on her cover art photo.

Her fans, who are known as her lambs, called her out for trying to look skinnier in the photo.

Check out some of their tweets below.

E! News even posted a collage photo of Carey's past album photos to show that the she may have been photoshopped to look like how she was in the past.

So far, Carey has not responded to the rumors.

She announced on Monday, April 13 that her greatest hits collection, "#1 to Infinity," is available for pre-order on her official website and will hit stores on May 18.

The album will feature 18 of Carey's number one singles along with a brand new track, "Infinity," which will come out on April 27, she wrote on Instagram.

The album is being promoted in conjunction with Carey's Las Vegas residency, which will debut on May 6 at The Colosseum at Caesars Palace. "#1 to Infinity" also marks her first album under Sony Music's Epic Records, with whom she signed with last month, Billboard reports.
