Alleged nude photos of Kate Upton and boyfriend Justin Verlander were leaked online Sunday as part of a massive celebrity photo leak.

The alleged nude photos show the Detroit Tigers ace and supermodel girlfriend naked in a bathroom standing side-by-side in profile with the mirror. Upton, who has twice appeared on the cover of Sports Illustrated’s swimsuit edition, is seen holding up a cell phone which she used to snap the pictures. 

Upton and Verlander first met while shooting a commercial for MLB 2K12 in 2012 and began dating soon thereafter. The two refused to confirm their relationship in 2012, and it seems like they broke up at some point later in the year or in early 2013. But the two got back together and began making numerous public appearances together at the beginning of the year. Upton has also gone to watch many of Verlander’s games this season.

Neither Upton nor Verlander have addressed the nude photos. Upton did not tweet at all on Sunday, while Verlander has not tweeted since last week. 

Numerous celebrities have been victims of the massive leak, with some confirming the authenticity of the photos and others saying they are fake.

According to BuzzFeed, the photos appear to have originated on a 4chan forum where they were posted by an anonymous user. The user claimed to have obtained the photos through an iCloud leak and was offering to sell them for Bitcoins. A master list posted by the anonymous user indicated they had photos and/or videos of around 60 celebrities.

The most prominent target of the leak was Oscar Award-winning actress Jennifer Lawrence, who had several nude photos hit the web. Her representatives confirmed the authenticity of the photos and threatened to prosecute anyone who posted or spread the photos.

Other celebrities allegedly victimized by the leak include Kirsten Dunst, Teresa Palmer, Becca Tobin, Jessica Brown Findlay, Krysten Ritter, Lea Michele, Ariana Grande, Brie Larson, Ali Michael, Mary Elizabeth Winstead and Victoria Justice. Athletes McKayla Maroney and Hope Solo were also alleged victims of the leak.
