In a new excerpt from Rebel Wilson's upcoming book, the actress sheds light on the alleged dislike between her and Grammy winner Adele, fueled by the constant size comparisons made about the two. Us Weekly exclusively obtained the revealing passage, where Wilson discloses that Adele likely isn't her biggest fan.

Over the years, Rebel Wilson and Adele have frequently been juxtaposed due to their respective body sizes. While Wilson admits to never confronting Adele directly about the alleged animosity, she shares that the "Rolling in the Deep" singer would consistently avoid her like the plague during industry events. This behavior has led Wilson to believe that Adele doesn't particularly like her.

Additionally, Wilson claims that Adele disliked being compared to Wilson's character in the "Pitch Perfect" franchise, the lovable and unapologetically named "Fat Amy." Both Wilson and Adele have undergone impressive weight loss transformations in recent years, with Adele specifically receiving both praise and criticism for her journey.

Interestingly, Adele isn't the only celebrity mentioned in Rebel Wilson's forthcoming memoir. In one controversial chapter, Wilson calls out Sacha Baron Cohen, making allegations against him and labeling him an "a**hole." With the book set to be released in just a couple of days, readers are eager to find out if any more prominent names will be dropped.

Rebel Wilson's revelations paint a picture of a complicated dynamic between her and Adele, driven by the constant scrutiny surrounding their sizes. As fans await the release of Wilson's book, it remains to be seen if these revelations will shed further light on the rumored tension between the two celebrities.
