Megan Fox goes viral as fans react to her changing appearance in Vegas selfie with Taylor Swift: 'What happened to her face?'

  • Fans commented en masse on pics of Fox, 37, that surfaced on Tuesday
  • She was seen in Las Vegas with partner MGK, 33, at a club 
  • Some commenters said they did not believe the person in the pics was Fox  

Megan Fox's name trended on social media on Tuesday after fans claimed they didn't recognize her in newly-surfaced pictures from her Sunday night celebration at Zouk nightclub in Las Vegas early Monday.

The Oak Ridge, Tennessee-born actress, 37, was with her fiancé Machine Gun Kelly, 33, as they celebrated with famous friends Taylor Swift, 34, and Travis Kelce, 34, after his Kansas City Chiefs won their second straight Super Bowl.  

A photo circulating from the revelrous outing in Sin City showed both couples posing with one another, posted by Joe Oravec, the managing partner of Barley House Cleveland.

In the pic, the Transformers actress and pop punk rapper flashed peace signs, as she sported pink hair worn up, a spiked collar necklace and a black shirt with an image of a skeleton's hand.

A number of fans remarked that Fox presented a drastically-different appearance than what they're accustomed to, going as so far as it question if it was even her.
